Unfortunately, there is no explicit and step-by-step spec to perform
the serialization of `color()` declared values, so while being
spec-informed, this is quite ad-hoc.
Fixes 81 subtests in:
- css/css-color/parsing/color-valid-color-function.html
Previously, a method with multiple sequence arguments would cause a
compile error, as the same variable name was redeclared when iterating
the sequence for each argument. This change disambiguates these
variable names.
This brings keyboard shortcuts for the inspector up with common
convention in FF and Chrome: Ctrl+Shift+C now also opens the inspector,
and F12, Ctrl+W, and Ctrl+Shift+I now close the inspector when the
inspector window is focused.
Resolves#972
Some websites (Reddit, for example) create lots of temporary documents
for fragment parsing. Before this change, we had to build a rule cache
for these documents just to determine whether there are :has, :defined,
or attribute selectors, while it should be safe to simply return `false`
right away.
Which will have proper handling of the exection context when performing
a microtask checkpoint. This fixes an assertion to be added in the next
commit where perform_a_microtask_check is invoked on a non-empty
execution context stack.
Instead of storing all storage objects in static memory, we now
follow the the spec by lazily creating a unique Storage object
on each document object.
Each Storage object now holds a 'proxy' to the underlying backing
storage. For now, this proxy is simply a reference to the backing
object. In the future, it will need to be some type of interface
object that stores on a SQLite database or similar.
Session storage is now correctly stored / tracked as part of the
TraversableNavigable object.
Local storage is still stored in a static map, but eventually this
should be factored into something that is stored at the user agent
level.
This is no longer done. One of the comments is also innacurate for a
second reason - the call stack is never empty in that case, and is
verified as such only a few lines above.
From what I understand, the suspension steps are not required now,
or in the future for our implementation, or any other. The intent
is already implemented in the spec pushing on another execution
context to the stack and leaving the running execution context as-is.
The resume steps are a slightly different story as there is some subtle
behavior which the spec is trying to convey where some custom logic may
need to be done when one execution context changes from one to another.
It may be worth implementing those steps at a later point in time so
that this behavior is a bit easier to follow in those cases.
To make the situation more confusing - from what I can gather from the
spec, not all cases that the spec mentions resume actually means
anything normative. Resume is only _actually_ needed in a limited set
of locations.
For now, let's just remove the unneeded FIXMEs that indicate that there
is something to be done for the suspension steps, as there is not, and
leave the resume steps as is.
This is consistent with other functions such as
HTMLElement::offset_width and fixes a crash for the included test.
Returning an offset of zero is not correct for this case, but this is
still an improvement to not crash.
This fixes a bug where, if a non-existent font family is specified in
CSS, whitespaces would be rendered using the emoji font, while letters
would use the default font. This issue occurred because the font was
resolved separately for each code point. Since the emoji font was listed
before the default font, it was chosen for whitespace characters due to
its inclusion of whitespace glyphs (at least in the Apple Color Emoji
font on macOS). This change resolves the issue by placing the default
font before the emoji font in the list.
This change fixes the IDLGenerators.cpp implementation of the “If
reflectedTarget's explicitly set attr-element is a descendant of any of
element's shadow-including ancestors” step from the “If a reflected IDL
attribute has the type T?, where T is either Element or an interface
that inherits from Element” case in the HTML spec at
http://whatwg.org/html/#reflecting-content-attributes-in-idl-attributes
This change updates the BindingsGenerator/IDLGenerators.cpp code to
handle reflected non-HTML::AttributeNames content-attribute names, and
to handle such names as-is — including names with dashes.
