This was a hack to percentages within tables relative to the nearest
table-row ancestor instead of the nearest table container.
That didn't actually make sense, so this patch simply removes the hack
in favor of containing_block()->width().
In #10434 an issue with leading whitespace in new lines after
a <br> element was fixed by checking whether the last fragment
of LineBox is empty.
However, this introduced a regression by which whitespace following
inline elements was swallowed, so `<b>Test</b> 123` would appear
like `Test123`.
By asking specifically if we are handling a forced linebreak
instead of implicity asking for a property that may be shared by
other Node types, we can maintain the correct behavior in regards
to leading whitespace on new lines, as well as trailing whitespace
of inline elements.
This works at the Token level, which is quick and easy but has
drawbacks: We don't know when something is a property name or a value,
or if something is part of a selector. But, this works for now.
We're using the outermost right and bottom child edges to determine the
width and height of the ICB. However, since these edges are *within* the
respective child's rectangle, we have to add 1 when turning them into
width and height values.
This fixes an issue where scrolling a document would shrink its viewport
rect by 1 pixel (on both axes) on every scroll step.
The only reason it wasn't const before (and why we had a const_cast
hack) was to support ImageStyleValue's constructor taking it, which no
longer applies. `hack_count--;` :^)
This always felt awkward to me, and required a few other hacks to make
it work. Now, the request is only started when `load_bitmap()` is
called, which we do inside `NodeWithStyle::apply_style()`.
Both at the same time because many of them call construct() in call()
and I'm not keen on adding a bunch of temporary plumbing to turn
exceptions into throw completions.
Also changes the return value of construct() to Object* instead of Value
as it always needs to return an object; allowing an arbitrary Value is a
massive foot gun.
The old versions were renamed to JS_DECLARE_OLD_NATIVE_FUNCTION and
JS_DEFINE_OLD_NATIVE_FUNCTION, and will be eventually removed once all
native functions were converted to the new format.
Previously we would ignore repaint requests that came in via OOPWV while
the WebContent process was busy with a previous paint request.
This caused some easy-to-trigger bugs where the painted content would be
"one paint behind", especially noticeable when scrolling.
This is similar to how Gecko avoids a reference cycle, where both the
NamedNodeMap and Attribute would otherwise store a strong reference to
their associated Element. Gecko manually clears stored raw references
when an Element is destroyed, whereas we use weak references to do so
automatically.
Attribute's ownerElement getter and setter are moved out of line to
avoid an #include cycle between Element and Attribute.
