Many thanks @andykmv and @dellus!

This is a perfect problem analysis and both of you are right.
This issue is indeed caused by the bounding boxes when the dimension label becomes too small.
The calculation of borders failed, when only on of the tolerance labels is set.
Then one edge of the bounding box is placed at 0,0.
When none or both tolerance labels are set everything is fine.

I opened an issue on github and can submit a solution soon:
