Safari 8 skips frames at end of sequence

[Lewitje]

As the slider reaches the final frames it seems to skip the last couple and glitch out.

I tested it in Chrome and Firefox and didn't experience the same problem.
I tested it with 10 frames, 30 frames, and 150 frames so I don't think it was an issue with the files being too large that could possibly be slowing down the browser.
