Small windows can cause phantom bytes to appear after animation.

[Zaleyact]

When a window is resized to be smaller when an animation is complete, it may cause more bytes to appear to the right in some cases. However, the animation cannot be played forward anymore.

To reproduce:

1. Go to the animation page and choose PLWAH, 32 bit
2. Paste 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000000000000 0000000000000000000000001000000 in as input
3. Play the animation all the way through
4. Make the window smaller, and big again
5. Observe that there are now new bytes to the right, despite the animation being complete.
