The issue cannot be reproduced on 19.10 daily (2019-10-14).
GNOME Shell 3.34.1
When trying to reproduce the issue by pressing a key repeatedly after pressing the suspend button, the locked screen will show for a short period of time (less than 2 seconds), then the system keeps going to sleep.
I think gnome-shell 3.34.1 do fix this, need to find out how to fix in bionic.
