266544 - scrolling with mousewheel stops when blog entry contains horizontal scrollbar

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Yusuf Goolamabbas]

Visit http://planet.gnome.org/
Keep the mouse pointer in the middle of the page where the text is
Use scrollwheel to scroll downward
When you reach Fredrico's blog entry which has a horizontal scroll bar 
in the page, the page stops scrolling (any direction) no matter how much you
turn the mouse wheel

This behaviour is not visible if the mouse pointer is kept on the right side of
the page (away from text) prior to beginning the scroll. Also when you are stuck
scrolling move the mouse pointer to the right and click. one can then resume
scrolling

I'm not sure how planet.gnome.org is constructed.  The problem is when there is
a wide <pre> section inside a "column".  I don't know if Planet Gnome uses a
table, or some CSS stuff.

text text text   |  sidebar
text text text   |  sidebar
<pre>            |  sidebar
this has some    |
very wide text   |
</pre>           |
text text text   |

The <pre> block gets its own scrolling area, and it seems to swallow wheel events.

This works for me just fine, however, on Firefox 1.0.0.  I recall seeing the bug
at some time or another, but I don't know in which versions.

I've been working on my site and came across this same bug.
In my case it has to do with the css overflow property for a div tag.
I've put together a simple example at: http://hagar.mine.nu/dump/overflow/

Attachment: test case

This is the same bug that Harm Geerts posted about.

The mouse scroll wheel does not work on <div> elements that have the overflow
property set to auto or scroll.

Bug remains in 1.0.4 -  this is getting infuriating, I know it's fixed in trunk
build 2005-03-11 but nobody's issued so much as a source patch!

Thomas, if something has been fixed in trunk then it's fixed. We don't backport
small changes like this to earlier builds. So go ahead and grab 1.5 beta 2 or
wait till 1.5 comes if you want to see this fixed. :)
