Reliable repro on the LineageOS 16 device (does not happen on Pixel 2 + Android 10):

* youtube in PiP
* on account screen
* tap email to open text input
* tap youtube (text input and keyboard close)
* tap email before navigation tray finishes closing (nothing happens)
* tap email again (keyboard comes up but text input isn't there)
