In practical terms, I'm unable to see any actual consequences of this difference. The logic seems reasonable to me, but I can't see any actual difference in behavior.

Would appreciate a 2nd opinion here, @westonruter or @adamsilverstein

This looks correct. Previously, if there was more than one popover opened at once, then the timeout ID in openTimeout would get clobbered by the second opened popover, meaning the first wouldn't ever automatically close.
