273581 - Mouse wheel will inappropriately scroll embedded ads

Status: VERIFIED DUPLICATE of bug 254972

(Firefox :: General, defect)

Description

[Trogdor]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

I notice that when using the mouse wheel to scroll up and down on many web
pages, if I happen to mouse over an ad, sometimes Firefox starts scrolling the
ad up and down a few pixels, rather than scrolling the whole page.


Reproducible: Always
Steps to Reproduce:
1.  Go to http://www.forbes.com/columnists/2004/08/06/cx_gk_0806artofthestart.html
2.  Use the mouse wheel to scroll up and down on the page
3.  Move the mouse to the vertically oriented ad to the right (for me, it's a
FedEx Kinko's ad today)
4.  Note that when you do a small scroll with the wheel, the ad scrolls up and
down instead of the page.


Actual Results:  
The ad scrolled up and down instead of the whole page.

Expected Results:  
Scroll the whole page.

This most likely occurs if the ad is served in an IFRAME. The iframe is being
scrolled when you mouse over it, not the page. That seems like the correct
behavior to me.
