IsSelectionEditable should check whether the focus node and anchor node
aren't null before trying to use them.
This also changes the initialization of selections' aOutIndex to the
last range in the selection as a fallback in case we don't add a range
later (in AddItem) which could also end up with a null selection
otherwise if the additional selection nodes are removed.
Since we are using vsync for timing anyway in the layout refresh driver,
there is no need to bump the system timer resolution down to 1 ms.
This resolves#1507.
whether they should be drawn.
This reduces the size of display lists for tables by only adding display
list items that are actually going to be visibly drawn, which will help
overall performance of table drawing.
There were actually two separate logical errors in this method:
The first part is that "origSizes.isSome()" is simply a bogus
requirement for applying min/max-sizes here. I'm still keeping
the optimization of not needlessly copying the mSizes array
(as originally intended) since it's a quite common case.
The second bug is that min/max-sizes were only applied under
the "if (fr != 0.0f)" block. This is bogus since the calculated
'fr' value depends on 'aAvailableSize' which might change by
applying min/max-sizes and thus 'fr' could become non-zero in
the second round.
To fix, this patch just moves "applyMinMax" block out one level.
This stub is added because websites insist on considering this
very hardware-dependent and O.S.-variable low-level font-control
as a "critical feature" which it isn't as there is 0 guarantee
that font variation settings are supported or honored by any
operating system used by the client.
On top this is a WD status feature that sites shouldn't be using, and
the feature itself is strongly discouraged for use in favor of standard
CSS font manipulation keywords like `font-weight`.
Do less work in PaintRowGroupBackgroundByColIdx for cells that are not in our desired set of columns.
crash fix:
Guard against empty column groups when building a display list for a table.
This changes the work we do for document.open() in the following ways:
- We no longer create a new Window when doing document.open().
We use the same Window but remove all the event listeners on the
existing DOM tree and Window before removing the document's existing
children to provide a clean slate document to use for .write().
- We no longer create a session history entry (previously would be a
wyciwyg URI). We now replace the current one, effectively losing the
entry for the original document.
- We now support document.open() on windowless documents.
This updates our behavior for computed DOM styling to no longer return
null on elements that have no display, but return a 0-length (empty)
style instead and don't throw. For this we stop looking at having a
presentation for the style and just look at the document instead.
This resolves#1219
forming a monotonically increasing sequence (e.g. with position:sticky)
Relative positioning can cause table parts to move, which can cause
issues with the cursor position to know which rows can be skipped.
To make this work, use the max difference between the frame's rect and
the union of the frame's "normal" position and the overflow rect to
cover the area of relatively positioned elements even if they are out of
order.
This resolves#1309.
list collisions when processing the background color of a table.
This is effectively #146 Part 3c to go along with the other 2 there.
This resolves#1308.
This also adds a reftest for border radius on collapsed borders (should
be ignored according to the CSS3 standard). We didn't do this before,
except on internal elements.
