171936 - scroll focus random

Status: RESOLVED DUPLICATE of bug 27771

(Core :: Layout: Form Controls, defect)

Description

[Pete Hammer]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.2b) Gecko/20020930

Scroll wheel focus seems to shift between the main window and scrollable text
form boxes at random.  Sometimes the scroll of the main page gets hijacked by a
scrollable form box just as that box is about to disappear off the top of the
window (Bugzilla's CC list especially).  This occurs sometimes even if the mouse
doesn't pass over the box.  Moving the mouse pointer out of the scrollable text
box doesn't move the focus back to the whole page, and sometimes even clicking
on the page outside the box doesn't shift focus back to the main page, and
sometimes this turns the scroll wheel action to selecting main page text instead
of scrolling. Similarly, in bugzilla's bug entry helper search window, if you
pulldown a selection box and scroll to the top or bottom, and keep going, the
scrolling selection box will draw, and then the scroll will pass on to the page
as a whole, tearing off the selection pulldown from the form-inside-a-form.

I get this on Win98 and Mac OS9.  On the Mac, scrolling sometimes works after a
delay of a second or two, and I have even seen the scroll event passed to a
Finder window BEHIND the mozilla window.  

Might be related to bug 27771, 94823 or 9086.

Reproducible: Sometimes

Steps to Reproduce:
1. Load page with scrollable form elements
2. scroll around

Actual Results:  
3. scroll events shift focus


Expected Results:  
scrolling effects should stay in the selected item, or default to the page as a
whole

bryner, this is all you.  ;)

reporter: is what you describe this still a problem with a recent mozilla build?
can you be specific about how this report is different from the problems
described in the other bugs you mention?

I haven't seen this in any recent builds, or in 1.2.1, so I suppose it could die
a quiet death...

well rather than just killing it as a WFM non-bug, I'll give it the recognition
it deserves, as a dupe of a real bug :)
