Can't exit split screen, navigation buttons don't work

The problem
Start split screen, choose 2 apps.
Type something into a text input field of one app. The focus is on the input.
Try to exit the split screen.
As soon as the keyboard is displayed the navigation buttons don't work anymore. You can swipe down in order to open the quick menu but you can't close it anymore – swiping up doesn't work. The only option to leave is either "deactivating" the focus or restarting the phone.
In this example screenshot I opened the system's settings and the clock. I clicked into the settings' search bar (you can't see the cursor because it's blinking) and the keyboard popped up. Fortunately, there is a back button but some apps don't have something like that so you are "stuck".
Ignore the top panel, it's just an scrcpy window (https://github.com/Genymobile/scrcpy)
