The touch caret frame is initialized at (0, 0). When <html> or <body>
has dir="rtl", "margin-left: -15px" (in ua.css) makes the horizontal
scroll bar appear even if the touch caret is invisible.
To compensate this, make width, height, and margin be 0px when the touch
caret is invisible.
* Replace png images with svg images for touch caret and selection
carets.
* Fix touch caret is enlarged on high resolution device due to
background-size was not set.
This assumes that the specification for how position:sticky behaves for
block-in-inline splits matches the specification for position:relative,
in other words, matches
http://www.w3.org/TR/CSS21/visuren.html#anonymous-block-level .
It's also necessary for patch 9b since the new rule for handling of
style change hints is that a style change hint applies to all
continuations and all block-in-inline siblings ("special siblings").
The change in StickyScrollContainer::GetScrollRanges is really the fix
for bug 918994, but adjusted for the change here to use block-in-inline
siblings ("special siblings") in addition to continuations.
Outer table frames act as CSS2.1 table wrapper boxes. We used to lay them out
without taking their margins into the account, which meant that their width was
always equal to the available width. This breaks horizontal positioning of
absolutely positioned kids of a table frame.
The main purpose of this patch is to apply the margins of tables to their outer
frame, instead of the inner frame. This means that the inner table frame will
always have a zero margin, which means that a lot of the stuff which used to
rely on the fact that table margins are applied to the inner frame need to
change.
In particular, in order to get the computed margins of a table, we used to query
the inner table frame, and this patch corrects that. Also, when shrink wrapping
tables, we used to not take the margins of the inner table frame into account,
which is fixed by this patch too. nsBlockReflowState::
ComputeReplacedBlockOffsetsForFloats also needed to be changed to read the
margin values from the outer frame too.
Also, as part of this patch, we start to respect the CSS2.1 margin model for
captions on all sides. This means that in particular, the top/bottom margins on
the top-outside and bottom-outside captions will not be collapsed with the
top/bottom margins of the table, and that the margins of the caption element
contribute to the width and height of the outer table frame. The
427129-table-caption reftest has been modified to match this new behavior.
Another side effect of this bug is fixing bug 87277, and the reftests for that
bug are marked as passing in this patch.
Change the quirks mode text-decoration code (soon to be used for all
modes) to follow CSS 2.1's rules for positioning of decoration lines.
Decorations are now drawn at a constant vertical position established by
the element creating the decoration, and more than one of the same type
(underline, overline, line-through) of decoration are supported on the
same piece of text.
This means that text-decorations can now significantly overflow a text
frame, since the vertical-alignment of the element with text-decoration
may be substantially different from the vertical alignment of the text.
Set overflow areas for text frames with text decorations in
nsLineLayout::RelativePositionFrames since it must happen *after*
vertical alignment is done, and when relative positioning data are
consistent (nsIFrame::GetRelativeOffset matches the offset that has been
applied).
