In
screen.py, the layout and scroll request flags were cleared after layout ran, so a resize watcher or layout subscriber that asked for another frame during layout lost the request. The flags are now read and cleared before layout. Separately,MessagePumpnow callsasyncio.sleep(0)after a delivery when more messages are queued, so one pump with synchronous handlers does not hold the UI thread. The same change moves theWidgetimport in message dispatch into the selector branch. Tests are added totest_refresh_callback_owner.py.
