Exclude system decor area from tap detection. 

If we have system decor (status bar/ navigation bar), we want to
exclude that from the tap detection. Otherwise, if the app is partially
placed under some system button (eg. Recents, Home), pressing that
button would cause a full series of unwanted transfer focus/resume/pause,
before we could go home.
