See the test case I'm attaching, and the URL for a real-world example. Desired behavior (IE 5 Mac/Windows, Netscape 4.77, Mozilla 0.7 2001010816): Each time foo.src is changed to 'image.gif', the 'image.gif' animation runs. Actual behavior (Mozilla 0.9.1 2001060712): After an animation has reached the end, it can never be restarted.

Although it might seem like a different bug, I think this is bug bug 17126 in disguise.

I can't run the test case attached to bug 17126, but from the summary it certainly sounds like the same bug. If an onMouseOver event handler can't reset the animation, it's no surprise that the onClick event handler in my own test case can't. I had checked the open bugs listed under Meta Bug 66966. I think 17126 belongs there too; I'll add it. *** This bug has been marked as a duplicate of 17126 ***

After further testing, I take it back; this is not a dupe of Bug 17126. This bug exists in Mozilla 0.9 but not in 0.7. Bug 17126's test case works the same way in both.

The test case in this bug is broken. Fix that and give the bug to me if you want (I'll probably get to it before pav)

The test case works for me. If you think it's buggy, I'll need more details.

Reassigning per comment #5, if you can still take it. Test case still works for me; if it's still broken for you please be more specific.

Giving back to Pav because I'm doomed and this is a cross platform bug. Resetting of the image.src should reset the animation.

Keyword per comment #1, platform per comment #8.
