hakim.elhattab@ Thanks for the issue.

Able to reproduce this issue on Windows 10, Mac OS 10.13.3 and Ubuntu 14.04 on the latest Stable 67.0.3396.99, Beta 68.0.3440.42 and latest Canary 69.0.3487.0 as per the original comment.

beccahughes@ Please check and confirm if this issue is related to your change, else help us in assigning to the right owner.

Adding 'ReleaseBlock-Stable' for M-68 as this is a recent regression. Please feel free to remove it if it is not applicable.

Thanks

This is unlikely to be that CL as we actually switch over to a whole new set of media controls in that bisect range.

We're not planning any further M67 release. Pls target fix for M68.

[Media Controls] Use zoom when calculating overlay play button hitbox

This CL modifies the overlay play button ShouldCausePlayPause function
to take CSS and Document zoom into account. This fixes a bug where a
zoomed video had an incorrect hitbox for the overlay play button.

Seems like this just landed on Friday. Has this been verified in canary yet? Once verified, is this safe enough to be merged to M68?

Chatted with steimel@, fix will be targeted for M69. 

Able to reproduce this issue on Windows 10, Ubuntu 16.04 and Mac OS 10.13.3 on the reported version 67.0.3396.99 and the issue is fixed on the latest Canary 70.0.3504.0 as per the original comment.

Able to click on the play button and the video starts playing.
Attached is the screen cast for reference.

Hence adding TE verified labels as the fix is working as intended.

Thanks..

As it is WAI on M70, please merge the fix to M69 if it is safe to merge.
Thanks..!

The fix should be in 69.0.3493.3. I will leave this open and let steimel@ confirms that there is nothing more to be done here when he is back.

M69 Stable promotion is coming VERY soon. Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and request a merge into the release branch ASAP. Thank you.

I've fixed the overlay play button issue, which was RBS, but there's a remaining issue with the overflow menu positioning. However, that is already stable in M68, so it's not a RBS. Therefore, removing the RBS label

FYI we're pulling the fix for the overlay play button since it's causing crashes. I have another solution that requires a significant refactoring so this won't be fixed in M69
