The main frame version (in WebViewImpl currently) takes care to not show a popup on GestureTap that was hidden as part of that gesture (on GestureTapDown). It has other differences too as the event handling goes to blink in each case then comes back to the HandleGestureEvent code, but in WebFrameWidgetImpl it goes to blink last.
We should make the behaviour consistent, and probably share the code.
FWIW this is widget code so it'll be moving out of WebViewImpl into a WebWidgetImpl at which point sharing is easier?
