Tapping fast on marker/highlight does not show menu
Possibly because the hover is not yet detected?
It looks like this delay already exists for selection completed (since we added the post build event).
Looking at the console log to trace the build, paint and display menu calls, it appears there's no extra "unexpected" work in between.
So it appears that we might not be able to do anything about it for the development build.
Double tapping a word does not emit the selection completed event. Therefore the selection menu disappear because always the last event will be selecting changed which is wired to call hideMenu()
