397871 - [FIX]###!!! ASSERTION: Negative width passed to nsWindow::Resize: '(aWidth >=0 )', file c:/suiterunner/mozilla/widget/src/windows/nsWindow.cpp, line 2155

Status: RESOLVED FIXED

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[[e-mail]]

Steps to reproduce problem:

1. seamonkey -mail

Only (sigh) on my non-debug build I can also trigger it by toggling the message pane (e.g. via F8).

Seems to be caused by the border on a collapsed <browser> element.

Hmm.  So I think we do want to PR_MAX this with 0 to handle border-box sizing with too-small width and the like.  But in this particular case, shouldn't the XUL code that does wacky things with |visibility: collapse| set the used border and padding to 0?

I don't see a sane way to do make the used border correct here; I'll just file a followup bug on that and hack in the PR_MAX here once bug 399410 lands.
