Controller navigation hacks: Transferring focus

Restoring the focussed element on dialog close is already handled by MUI, we
don't need this code ourselves

Moving focus on dialog open *should* work automatically as well, however it
doesn't. I've tried various methods with element properties and JS, nothing
seems to work. As a band-aid fix for now, we simulate 1-2 tab presses to focus
the dialog content
