Status: RESOLVED DUPLICATE of bug 332973

(Core :: Graphics: ImageLib, defect)

Description

[Peter Brodersen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

A stopped gif animation will continue if a link to a page containing the same
gif is opened.

Gif animations can be stopped by pressing escape. When another page references
to the same URL, the gif animation continues on the page where it has been stopped.

Reproducible: Always
Steps to Reproduce:
1. Go to http://stock.ter.dk/anim_1.php or create a couple of pages with the
same gif animation
2. Press escape to stop the animation
3. Open a new tab where the gif animation is present

Actual Results:  
The gif animation continues on the page where it has been stopped

Expected Results:  
The gif animation should still have been stopped.

The problem is present in Mozilla 1.7 as well, and Firefox 1.0 under Linux.

It might be related to the behaviour mentioned in bug #129986

If it's the same image, imagelib will only allow us to animate it in all windows
or not animate it in all windows....  It only has a single object for the image.

Then it sound like imagelib needs to be able to represent
different occurrences that are of the same images but that
have different states (e.g., moving vs. stopped).

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
