Hide display feature incorrectly blocked in workout mode

I usually ride with the companion app and used to use zwift-preferences to remove the screen clutter. This has been taken away and I can’t switch off the UI in workout mode which I use 100% the time.
There’s absolutely no reason to disallow this in workout mode. If a user presses H in workout mode they must have a good reason for doing so (e.g. they are using the companion app). If it was by accident, it’s easy to press ‘H’ again.
Blocking this in workout mode is the wrong behavior, there’s no sensible reason for doing it.
