[Safari] Some YouTube videos sometimes don't play

[DAddYE]

When I browse to youtube and there are ads within the video I cannot play it.

• A URL where you confirm the issue occurs
• Your selection of filter lists
• Your custom filters
• Your dynamic filtering rules, if any
• Browser/version

@DAddYE I've run a bunch of tests with µBlock for Safari on YouTube.com and have faced no issues. Please provide steps to reproduce — your selection of filter lists, custom filters, browser and µBlock version.

Hi sorry for the lack of details, sometimes it happens on any video sometimes (after I opened the issue) it doesn't.

Found right now one: https://www.youtube.com/watch?v=NJLrcG64ulU

I'm on Safari 8.0.3. Nothing in My Filters and nothing in My Rules.

I think I have just the default filters enabled here a screen of those active:

To add more seems that when ublock is active it raises this issue (on the link provided)

@DAddYE ah, got it. It looks like this was caused by the same thing as #878 — the fix is 8397512 and will be in 0.8.9.3. It's not in 0.8.9.2, though.
