Fixed an issue where the heads up were not rounded during bypass

When huns are above the shelf, their rounding should not be modified
Currently they are unrounded by the shelf in certain conditions
which didn't unclude the bypass heads up.

Fixes: 192057822
Test: add hun on lockscreen with bypass, observe no wrong rounding
