It’s probably fine, but you can accidentally short it when moving it around by touching it or resting it up on something conductive, even if you’re careful dust might short it as well, but this is much rarer.
As a general rule I would try to avoid it, but would not be my first concern.
One thing I find very interesting about how brains process reality is that there’s a disease that makes your eyes have blind spots. However people with that disease don’t see those blind spots because the brain fills the gaps with the information it knows to be there. So you could see a door closed just as it was when you last looked at it directly, but in the meantime someone opened the door and you’re still seeing the door closed until you look at it directly.
