2.2.0 RC5 - Height range modifiers not working

Version

2.2.0 RC5

Operating system type + version

Windows 10

Behavior

Height range modifiers are not being applied. When setting the external perimeter speed for a single wall cube, the speeds remain the same throughout the print. This can be seen on the preview, and I also reviewed the Gcode and can see that this is the case:

The legend has the speeds correctly from 20 to 50 mm/s, but the speed remains in all the print to 20mm/s.

Project File (.3MF) where problem occurs

Doing the same using modifiers works as expected:

It is related to "clip multipart objects" parameter. Enable this parameter to fix the issue.

It will be enabled by default in PrusaSlicer 2.2.0 final. See #2803. Closing.
