368641 - "ASSERTION: node in map twice" with xul:tabs, xul:popup, xul:template

Status: RESOLVED FIXED

(Core :: XBL, defect)

Description

[Jesse Ruderman]

Attachment: testcase

Loading the testcase triggers two assertions:

###!!! ASSERTION: Already have an undisplayed context entry for aContent: '!GetUndisplayedContent(aContent)', file layout/base/nsFrameManager.cpp, line 592

###!!! ASSERTION: node in map twice: 'Not Reached', file layout/base/nsFrameManager.cpp, line 1695

It also triggers a pair of warnings:

WARNING: Inline(span)(3) frame didn't implement GetPrefWidth: file /Users/admin/trunk/mozilla/layout/generic/nsFrame.cpp, line 2929
WARNING: Inline(span)(3) frame didn't implement GetMinWidth: file /Users/admin/trunk/mozilla/layout/generic/nsFrame.cpp, line 2915

This is basically the same issue as bug 368276 -- we're ending up doing a containing block reframe because of the {ib} split, so we end up with the frames for the <span> in two different places in the frame tree.
