220718 - mousewheel scrolls innerHTML when it should not

Status: RESOLVED DUPLICATE of bug 259615

(Core :: CSS Parsing and Computation, defect)

Description

[Steve Theodopolopolous]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20030929 Firebird/0.7+ (aebrahim)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20030929 Firebird/0.7+ (aebrahim)

Win2ksp4. When using DThread mode on http://www.shacknews.com/latestchatty.x and
collapsing a thread, the mouse-wheel should always scroll the *whole page* up
and down. However, when using the mouse-wheel over a *collapsed* thread, the
mousewheel scrolls the text *inside* the collapsed thread, rather than the whole
webpage.

IE does not behave like this.
FB 0.6.1 did not behave like this.

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.shacknews.com/latestchatty.x
2. Using the pulldown menu, set mode to "DThread"
3. Find a post that has 4 or 5 lines of text in it, and collapse the thread
(using the [+-] icon on the left hand side of the post)
4. Hover the mouse over the area of the collapsed thread and roll the
mouse-wheel up and down to scroll the page up and down.
Actual Results:  
The text *inside* the collapsed thread is scrolled up and down with the mouse-wheel

Expected Results:  
The text inside the collapsed thread should *not* be scrolled. The whole page
should be scrolled as per usual. The collapsed thread should show the first line
of the post only; you should not be able to scroll through the collapsed
thread's text.

-> style system, dbaron (because he fixed bug 69355).

If this is just the opposite of bug 69355, it might be wontfix.

We probably shouldn't scroll scrollframes with 'overflow: hidden'.

I thought CSS was just for styling?

I'd have found this if it had had a better title.
