Cutting mesh breaks overlapping volumes

Reproduction steps

Adding a cutting mesh anywhere in a scene even if it doesn't overlap other models breaks the "Union Overlapping Volumes" check

Here is the example 3mf file:

Actual results

Result the overlapping meshes get cancelled out:

Expected results

This is probably the worst case for behavior, as we would not expect it to actually remove the middle of a model, but ideally this isn't affected by adding a cutting mesh at all.

If I remove the cutting mesh this works just fine:

Thanks for the report.
I had never noticed this. Playing with the cutting mesh cylinder, I moved it up above the merged model and the problem went away.

The Cura team will take a look.

This is with a regular support block configured as a cutting mesh. The problem starts when the layer height reaches the cutting mesh. Since it was off the build plate, it left a pocket. In addition, enabling "Remove all Holes" made the problem go away.
