XY Separation > 50% causes floating supports

2.3.0-rc2+win64

Windows 10

Custom CoreXY Printer

When setting the XY separation between an object and its support to more than 50%, the supports aren't generated properly.

Example with 60% separation:

Example with 150% separation:

Working example with 50% separation:

Note that the issue doesn't seem to be present with PrusaSlicer 2.2.0+win64.

Load the attached 3mf file
Slice the project, then observe layer number 58. You need to set the viewport to ISO and then rotate it 180° to see the affected area.
If you set the separation to 50%, the supports are generated correctly

It is better, but there are still some unsupported dense interfaces with PrusaSlicer 2.4.0-alpha3

It was broken with 96b88f5b29f14d23f022d627b62e7c64883dcef8 after alpha1, now fix again with 5de143f04fdb586490b28a4ac60654a1bb964a37
