isExposed() returns 'true' in cases where the documentation says it should be 'false'. E.g. when you minimize or cover it completely it returns false on Linuxes.

Steps to reproduce:
1. run the attached example
2. minimize the app
3. check the debug output when app is minimized

Expected result:

• isExposed() should return 'false' when the app is minimized

Actual result:

• isExposed() returns 'true'

This bug is making the autotests in the CI to be flaky and is slowing down the integration, that's why it's marked as P0.
