Move the "Parent" folder into the "Child" folder let's make that impossible in the UI.
Thanks for finding these, @AndiAJ ! I really should have thought of this case earlier :) Should be fixed by https://github.com/mozilla-mobile/fenix/pull/15363 once that lands.
Verified as fixed on Nightly 200925 06:01 GV 83.0a1 from 9/25 with Motorola Moto G6 (Android 8).
I will close this issue and remove the qa:needed label.
Reproducible on RC 81.1.2 using a OnePlus A3 (Android 6.0.1)
