It looks like the refactoring for tap-text-extract in CL 2703473002 caused a regression in the panel metrics so now chained taps are not being counted as separate searches. This will throw off our metrics, so it needs to be fixed soon.
Investigating. It looks like the previous implementation relied on animation start/finish to track the retap by calling setPanelState, but the new code evidently doesn't animate the panel on a retap so ContextualSearchPanelMetrics.onPanelStateChanged doesn't get called.
