255138 - Reflow absolute children of relative positioned inlines during nsLineLayout::RelativePositionFrames

Status: VERIFIED DUPLICATE of bug 255139

(Core :: Layout, defect)

Description

[Robert O'Callahan (:roc) (email my personal email if necessary)]

Because horizontal alignment of inline frames can change their widths, absolute
children of relatively positioned inlines should be reflowed after horizontal
alignment. nsLineLayout::RelativePositionFrames would be a good place to do
this; we can't do it any later, because we need to compute the correct overflow
area in that method.

Also, if we do this, then line layout does not need to record the overflow area
of frames or spans in the per-frame or per-span structures, because all overflow
areas will be entirely computed on the fly in RelativePositionFrames. This will
save space and simplify code.
