101518 - Mozilla freezes after setting style.display to none

Status: RESOLVED WORKSFORME

(Core :: DOM: CSS Object Model, defect)

Description

[Simon Weijgers]

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.4) Gecko/20010913
BuildID:    2001091311

Basically I'm setting the display property of a bunch of <tr>'s
to `none' and `block', switching every second.

It chokes on the third pass (on the first tr element) as demonstrated by:
http://www.weijgers.com/testcase-freeze-improved.html

I tested the test case on mozilla/0.9.3 (linux) and mozilla/0.9.4, it froze both.

People on #mozilla reported that it also freezes w2k/mozilla.

Reproducible: Always

Confirming that this also freezes current BRANCH 0.9.4 on Red Hat Rawhide Linux.

This also freezes yesterday's TRUNK snapshot (on Linux).

It hangs when style display='block', and then display='none'
Here is very small example

BTW, bug is in my code (td display must be table-cell). But what happens with
mozilla ? :) I check it with mozilla 0.9.3 and mozilla 0.9.4 builds.

Alex, only the bug assignee is supposed to change the status of his/her bugs from
NEW to ASSIGNED, please never do that again to bugs that are not assigned to
you. Thanks.
