285059 - Event handling gets stuck after page content dynamically changes via JavaScript

Status: NEW

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[S. Tringali]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1

This may be a website bug, but it makes it look like Mozilla/Firefox is not
responding.


Reproducible: Always

Steps to Reproduce:
1. Go to http://forum.mazda6club.com/
2. Collapse a category by making a single click on one of the "+" buttons on the
right.  Do not make any other clicks.
3. Attempt to use scroll wheel.
4. Attempt to do a search with accelerator ^F
5. Now click on some plain (non-button) text in the page.
6. Try to scroll again - it works now.
7. Try ^F again - it works too.

Actual Results:  
At step 3, no scrolling happens.
At step 4, no search bar is opened.

Expected Results:  
At step 3, scroll.
At step 4, open search bar.


The workaround (make an extra click) is easy, but it's not obvious.  This
happens both in Mozilla 1.7.5 and Firefox 1.0.

Yeah, looks like focus goes away somewhere here...

Could use a minimal testcase, as usual.  ;)

Attachment: Testcase

The scroll wheel works for me in current trunk builds.
Didn't work in: 2004-08-06 07:00:00
Works in: 2004-08-07 09:00:00
Probably that one is fixed by bug 97283, I guess.

Confirming.  Mats, Bryner, Aaron, any idea what's up here?
