Instead of recalculating styles for all nodes in the common ancestor of
the new and old hovered nodes' subtrees, this change introduces the
following approach:
- While calculating ComputedProperties, a flag is saved if any rule
applied to an element is affected by the hover state during the
execution of SelectorEngine::matches().
- When the hovered element changes, styles are marked for recalculation
only if the flag saved in ComputedProperties indicates that the
element could be affected by the hover state.
Previously, `percentage_of` would be called on the previous value,
potentially changing its numeric type, yet this potential change
was never reflected as the old numeric type was always used. Now,
the numeric type will be re-calculated every time after the
percentage is resolved. As well, VERIFY checks have been placed to
uphold the requirements for the numeric types to match what the
actual values are.
The "strictly split" infra algorithm feels like an inefficient way of
doing basically what our existing split() does, except working with
code points instead of bytes. It didn't seem worth it to implement now.
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.

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.
