Before page_did_create_main_document() only initialized ConsoleClient
for top-level browsing context which means that nested browsing context
could not print into the console.
With this change, ConsoleClient is initialized for documents created
for nested browsing context too. One ConsoleClient is shared between
all browsing contexts within the same page.
Which for now will just call the DeprecatedString version of this
function. This is intended to be used in porting code over to using the
new String equivalent with the end goal of removing the DeprecatedString
version of this function.
This allows us to port a whole heap of IDL interfaces from
DeprecatedString to String.
User styles are applied after the UserAgent's built-in styles, and
before the Author styles that are part of the web page.
Because they're neither part of the page, but can still be modified
while the page is open, caching is a little tricky. The approach here
is to piggy-back on the StyleComputer's rule caches, which already get
rebuilt whenever the styles change. This is not the smartest approach,
since it means re-parsing the style sheet more often than is necessary,
but it's simple and works. :^)
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
This invariant is enforced by the fact that `NonnullGCPtr` can only be
constructed from references.
This commit fixes an instance where we compared a pointer to null after
we have already dereferenced it.
This makes event handler to try to find scrollable paintable in the
chain of containing blocks of hit box. This is very naive and will
have to be improved in the future.
Click event logic should start as false, and after checking if the
mousedown and subsequent mouseup have been on the same element, and if
the node dispatches events it can become true.
This fixes the issue that clicking anywhere on the page, then dragging
the mouse on top of a link or button, then releasing triggers the link.
This is also happening when selecting text, if the selection stops over
a link, the page navigates.
Using fixed-point saturated arithmetics for CSSPixels allows to avoid
accumulating floating-point errors.
This implementation is not complete yet: currently saturated
arithmetics implemented only for addition. But it is enough to not
regress any of layout tests we have :)
See https://github.com/SerenityOS/serenity/issues/18566
The data we want to send out of the WebContent process is identical for
audio and video elements. Rather than just duplicating all of this for
audio, generalize the names used for this IPC for all media elements.
This also encapsulates that data into a struct. This makes adding new
fields to be sent much easier (such as an upcoming field for muting the
element).
Although DistinctNumeric, which is supposed to abstract the underlying
type, was used to represent CSSPixels, we have a whole bunch of places
in the layout code that assume CSSPixels::value() returns a
floating-point type. This assumption makes it difficult to replace the
underlying type in CSSPixels with a non-floating type.
To make it easier to transition CSSPixels to fixed-point math, one step
we can take is to prevent access to the underlying type using value()
and instead use explicit conversions with the to_float(), to_double(),
and to_int() methods.
Introduce has_ongoing_navigation() that allows to check if resource
state in FrameLoading is pending. This API is going to be used in
upcoming fix for wait_for_navigation_to_complete() in WebDriver.
BrowsingContext::set_active_document() may end up asking for the Page's
top level browsing context before Page has one. Do a workaround for now
where we have an API to ask if it's initialized.
Long-term we should find a cleaner solution.
This fixes a plethora of rounding problems on many websites.
In the future, we may want to replace this with fixed-point arithmetic
(bug #18566) for performance (and consistency with other engines),
but in the meantime this makes the web look a bit better. :^)
There's a lot more things that could be converted to doubles, which
would reduce the amount of casting necessary in this patch.
We can do that incrementally, however.
This now allows websites such as Discord, YouTube and your favourite
"Right Click" xkcd comic to open a custom context menu when you right
click. You can bypass this by holding shift, just like Firefox.
This allows for the browser process to control the play/pause state,
whether we paint user agent controls on the video, and whether the video
loops when it finishes playing.
This just sets up the IPC to notify the browser process of context menu
requests on video elements. The IPC contains a few pieces of information
about the state of the video element.
This can occur if a mouse click on a mouse event tracking node causes a
page navigation. As the old document is torn down, the event handler may
have a stale reference to the tracking node. If a subsequent mouse event
occurs on that node, we would crash trying to access the node's styled
properties that are no longer valid.
To fix this, when we are deciding what node to send the event to, and we
have a mouse event tracking node, check if that node still wants the
event. If not, clear the tracking node.
The "browsing context container" concept in the HTML spec has been
replaced with "navigable container". Renaming this is the first step of
many towards implementing the new world.

This ports MouseEvent, UIEvent, WheelEvent, and Event to new String.
They all had a dependency to T::create() in
WebDriverConnection::fire_an_event() and therefore had to be ported in
the same commit.
LibGUI and WebDriver (read: JSON) API boundaries use DeprecatedString,
so that is as far as these changes can reach.
The one change which isn't just a DeprecatedString to String replacement
is handling the "null" prompt response. We previously checked for the
null DeprecatedString, whereas we now represent this as an empty
Optional<String>.
The name "initial containing block" was wrong for this, as it doesn't
correspond to the HTML element, and that's specifically what it's
supposed to do! :^)
