So am I doing something wrong or is it a bug?
Of course, it is a bug. I confirm the repeatability.
Please make a ticket in the tracker with a link to the thread so that the file does not get lost.
Trimming relies on a buggy OCCT function. It has been reported to OCCT, but not fixed yet.
There is some code in FreeCAD that tries to compensate for this OCCT bug. Maybe it can be improved to handle this case.
