s/clientWiillPausePlayback/clientWillPausePlayback/

Also, this line is really long.

Why not TaskSource::MediaElement?

Why not pass a PlatformMediaSessionManager::DelayCallingUpdateNowPlaying instead of a bool? Or maybe define the enum in this class and use it in PlatformMediaSessionManager

Thanks for the review Eric, I took it all!
As of iOS failure, this is due to the test simulating scrolling but waiting for an event while scrolling.
Given scrolling is suspending DOM objects, events cannot really happen during that time. I updated the test accordingly.
