No grid in xz- and yz- snapped mode

In snapped mode, for normal, you should see the grid if you snap the view via the orientation cube. Of course, only if you show the grid.

However, after a while it is not showing anymore. I have to kill nomad (close it from the recent app overview) and start nomad again.
The xy-grid is always shown.

Android 13: Galaxy Tab S7

The first two screenshot show the missing grid - the latter two how it is after a fresh nomad start.
