373566 - Ascent of box-wrapped IMG is absurdly large

Status: RESOLVED INVALID

(Core :: Layout, defect)

Description

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

Attachment: testcase

See attached testcase. Essentially the NS_INTRINSICSIZE we pass to BoxReflow here:
http://lxr.mozilla.org/seamonkey/source/layout/generic/nsFrame.cpp#5829
gets propagated around and eventually returned as the ascent of the image. This causes bad things to happen.

what kind of "bad things"? "fix on the branch" bad things?

Content to disappear. Probably nothing that couldn't be triggered in other ways though.

But I think this is related to reflow branch and may not be present on branch.

This works for me on trunk and on a right-after-reflow-branch landing build.

And I'd have thought this would have been fixed by bug 366667.
