The `to_string()` for this is modified a little from the original,
because we have to calculate what the layer-count is then, instead of
having it already calculated.
The existing implementation has some pre-existing issues where it is
incorrectly assumes that byte offsets are given through the IDL instead
of UTF-16 code units. While making these changes, leave some FIXMEs for
that.
This is required in porting over CharacterData from DeprecatedString to
String.
Unfortunately, as with ParentNode, we cannot yet remove the
DeprecatedString variants of these functions as the Element interface
includes ChildNode and has not yet been ported over from
DeprecatedString.
This allows applying SVG <mask>s to elements. It is only implemented for
the simplest (and default) case:
- mask-type = luminance
- maskContentUnits = maskContentUnits
- maskUnits = objectBoundingBox
- Default masking area
It should be possible to extend to cover more cases. Though the layout
for maskContentUnits = objectBoundingBox will be tricky to figure out.
This allows SVG mask elements to have layout computed, but not connected
to the main paint tree. They should only be reachable if (and painted)
if referenced by the "mask" attribute of another element.
This is controlled by the forms_unconnected_subtree() function on the
paintable, which (if it returns true) prevents the paintable from being
added as a child to what would be its parent.
A Paintable is not created for an SVG <defs> element (nor should it),
but it can contain SVG <mask> elements that need a paintable.
This change forces those paintables to be created (without a parent).
The masks are then only painted by being referenced from another
element.
We were parsing these all right, but ignoring them in StyleComputer.
No test unfortunately, since we don't currently have a way to delay
the load event until a @font-face has been fully loaded. (Any test
of this right now would be flaky.)
This fixes an issue where the value would be out of sync with reality
in anonymous wrapper block boxes, since we forgot to compute m_visible
after assigning the computed values to them.
Fixes#21106
Support for this element has been removed from all major engines years
ago already, and it's currently the only reason we have a weird
"visible" flag on Layout::Node (which we toggle on a timer here..)
Some websites, such as m.youtube.com, sniff for a version after the
Android OS version. Chrome has recently taken to always reporting
Android 10, so let's follow suit.
Some steps are still to be implemented, namely:
* Properly aborting the read algorithm
* Handling BinaryString type properly
* Setting error on any error
But as it stands, this is enough functionality for the basic case of
reading the contents of a blob using the FileReader API.
ArrayBuffer no longer stores a plain ByteBuffer internally, but a
DataBlock instead, which encapsulated the ByteBuffer together with
information if it is shared or not.
This adds initial support for `open-quote`, `close-quote`,
`no-open-quote` and `no-close-quote`. We don't yet track the "nesting
level" so we always use the first pair of quotes from the `quotes`
property.
After moving to navigables, we started reusing the code that populates
session history entries with the srcdoc attribute value from iframes
in `Page::load_html()` for loading HTML.
This change addresses a crash in `determine_the_origin` which occurred
because this method expected the URL to be `about:srcdoc` if we also
provided HTML content (previously, it was the URL passed along with the
HTML content into `load_html()`).
This allows us to get rid of property_table_ordered() which was a
heavy-handed way of iterating properties in insertion order by first
copying them to a sorted Vector.
Clients can now simply iterate property_table() directly.
3% speed-up on Kraken/ai-astar.js :^)
Fixes regression introduced in b4fe118dff
The `WebContentConsoleClient` needs to be created not just once, but
for every new document. Although the JS Console window allows
communication only with the active document associated with the
top-level browsing context, we still need a console client for each
iframe's document to ensure their console logs are printed.
In the future, we might consider adding the ability to switch which
document the JS Console window communicates with.
Fixes https://github.com/SerenityOS/serenity/issues/21117
If `load_document()` is called with a response that has a mime type we
can't use to build a document, we should return nullptr as the spec
says, instead of crashing. Also we should not crash if error happened
during parsing.
