dbbrooks@ and I did some follow up here.

We can repro this on Chrome 64, but also on Chrome 62.  I don't know if the revert change noted in the description was also pushed back to Chrome 62 or something else, but the current actual behavior seems to have been in place for some time.  (leaving it tagged as a regression for now, but if the reporter can also repro in earlier versions I would suggest changing to a standard bug)

It does feel like something is odd with the touch targeting, something like touch events last a little bit longer than expected and so propagate down to the next element underneath what ever was just touched if the first element was dismissed by the touch.

But this isn't a stable blocker and feels at best to be a P2 as it's a visual annoyance but doesn't impact functionality otherwise, updating labels accordingly.
Agree that this should not be flagged as stable blocker.
