Symbol Marker for points offset when using "Map Units" or "Meters at scale"

[chleidersdorff]

What is the bug or the crash?

When you switch from millimetres to a meter at scale or map units the point symbology is offset from the centre location.

It seems to be isolated to the map legend in the preferences.

Steps to reproduce the issue

1. open point file
2. set project to meters projection
3. change symbology from millimetres to meters at scale or map units

I confirm this issue persists in version 3.28.11-Firenze and 3.32.3-Lima. I found a workaround by keeping map units for the simple marker size but setting both the line thickness and offset to millimeters (my interface is in italian, but you can get the point): Unfortunately, doing so changes the unit to millimeters for the marker, so while the simple marker scales according to the map scale, the active area to select the marker by clicking remains unchanged:
