Comment 37 for bug 722285

I've had a look at this patch, and while it does fix the limitation, it breaks another aspect of the timeline scroll behaviour. Normally when the timeline is longer than what is visible, the timeline 'auto' scrolls while playing, so that the playhead stays in the center of the timeline. This seems to be broken with this patch, the playhead disappears to the right.

If I get a chance I'll try and take a look at working out why. But I don't want to apply the patch while it breaks something else.
