Fixes missed RequestRedraw events in about_to_wait()

Browse Source 
This fixes RequestRedraw events that can be missed in `about_to_wait()` which was reading from the cursor before `run_app_update()` is called.

This adds a subsequent read to update the redraw_requested flag if any `RequestRedraw` were sent.

Was reported in #16817
