@traynard, could this be related to #3932? It brings up the bottom bar when the bottom edge of the screen is tapped. Safari should behave the same IIRC. Are you able to tap the "expand" link as soon as the bottom bar is visible?

If this is indeed caused by #3932, we'll need to find a solution for those edge cases. E.g. when tapping the bottom edge of the display, only bring up the bottom bar if the tap can't be propagated to a tapable element within that area.

@mario It definitely seems to be related to #3932.

in Safari: When you tap on the "Comments" section on youtube (to stick to the example), the bottom bar does become visible. However, it pushes up the content so the "Comments" section is resting above the bar and allows users to interact with it.

in ABB: When you tap on the "Comments" section on youtube, the bottom bar becomes visible and overlaps the comments section. This disables users from interacting with it in any way. If you attempt to scroll up to access the comments section, the bottom bar disappears and the cycle begins again.

@traynard, Ahh, that makes sense! Thanks for comparing both. I think we should adopt Safari's behavior, as it mitigates the problem in a nice, straight-forward way. I'll rewrite the ticket slightly to reflect this.

@mario - Yeah, i agree. Sounds good, thanks!
