@MisterMakerNL Can you take a look at this? It definitely needs to be fixed for 1.0. Maybe even #13697 should be reverted?

Why oh why does this not happen when you use a stylesheet?
Anyway, is easy fix since I can export these images from a svg file.
I also do not understand why I didn't see (Looked fine on my side) this issue as I had compiled freecad a gazillion time after this PR. Maybe it picks it out of my stylesheet folder?
