194904 - Mousewheel scrolls the <marquee> :)

Status: VERIFIED FIXED

(SeaMonkey :: General, defect)

Description

[Marek Stępień [:marcoos, inactive]]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3b) Gecko/20030222

Sometimes using the mousewheel does not scroll the page, but... the contents of
the <marquee> tag!

Is this a bug or a feature? :)


Reproducible: Always

Steps to Reproduce:
1. Go to a website that uses vertical <marquee>, e.g. http://www.jabberpl.org/
2. Right-click on a link inside the <marquee> and afterwards close the pop-up menu.
3. Scroll your mouse wheel up and down

Actual Results:  
Mozilla scrolls the marquee! (But it's fast enough, so the marquee "jumps").


Expected Results:  
Do not touch the marquee and scroll the content of the page instead. :)

Tested on GNU/Linux. Haven't checked other platforms.

Either way.   ;)

Does www.jabberpl.org exist? doesn't seem to for me

Comment 3

[Doron Rosenberg (IBM)]

its because we use an iframe due to performance reasons :)  I'd have to add
event handlers and preventDefault or something.

To comment #2:

JabberPL.org does exist. Sometimes it just has some problems with DNS, but it
should be always available at http://jabber.itn.pl/

[Jeremy Rand]

Um . . . http://www.jabberpl.org/ doesn't have any <marquee> tags . . . .

Jeremy:

But it had one when this bug was being submitted. ;)

Comment 7

[Jeremy Rand]

Yeah, but since it currently doesn't, I can't see what the bug is.  Could
someone create a testcase?

Attachment: Vertical marquee testcase

Here comes the testcase.

BTW. I've just noticed that this bug does not appear in Mozilla for Windows,
but it does appear in Linux version.

Also seems to occur in OS X

IMO, this is feature, not a bug. In fact, I have at times felt the need to stop
a marquee to be able to scroll it or to do a selection. A "pause" item in the
context menu would be nice.

I can't scroll the marquee anymore with my mousewheel, using:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8a5) Gecko/20041020
Firefox/0.9.1+

I believe this was fixed by the fix for bug 259615.
The marquee code uses a anonymous overflow:hidden div.

Verified with a l10n nightly build of Firefox (aviary branch).

Mozilla/5.0 (X11; U; Linux i686; pl-PL; rv:1.7.3) Gecko/20041020 Firefox/1.0

[Marek Stępień [:marcoos, inactive]]

Strange, I tried the testcase again and I can still scroll it. Don't know why it
didn't scroll previously. :)

Comment 14

[Martijn Wargers (dead)]

Marek, this is fixed in trunk builds (1.8a), not in branch builds (1.7). 
You should try a nightly 1.8a build to see that this is fixed (if you then still
can see that you can scroll the marquee, then you can reopen the bug).

Now verified with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a5) Gecko/20041112.

I still wonder why it seemed fixed to me in Firefox. :)
