javascript error while reloading during animation

[JorisDebonnet]

It's really nothing serious, but something very slightly goes wrong, so I thought I'd just report it.

When you reload a page that is currently doing an animation, you get a javascript error. Probably because jQuery is still trying to reference something for the animation that has disappeared in the meanwhile.

Since the 'reloaded' page works as it should, it's certainly not a big thing. Only that I get red messages in some addons that are tracking errors.

It may be easy to fix though, although I'm not sure whether it would cause any performance issues (if an additional check is required on every step).

The 'error' happens on current line 8400, where it merely says:

if ( timerId )

I see an illegal invocation error caused by your setTimeout trying to execute location.reload

Is this in a particular browser? I've tested all of them after removing your setTimeout and I see no errors.

Do you reload the page though?

Here's a slightly changed version where you can reload by clicking the button (but you can of course just reload the page/frame yourself):

I see the errors appear in Firebug and in Webdeveloper Toolbar, in Firefox 4.

The error is: "attempt to run compile-and-go script on a cleared scope".

I've verified this, but it looks like a bug in Firefox to me. Seems like FF must not be stopping the timer. It's beyond our abilities to control I would think. Can you report it to Mozilla?

[JorisDebonnet]

You probably have a point. I have reported it as a Firefox bug right here: ​https://bugzilla.mozilla.org/show_bug.cgi?id=661405

Let's see what they say :)

As this is an issue with Firefox itself and is currently beyond the scope of our ability to fix, the ticket is being closed as cantfix. Should we however discover at a later point that there is a core patch that can be applied to fix the behaviour experienced, please feel free to re-open.
