Can confirm, also experiencing this on some models.
I was able to reproduce this in PrusaSlicer 2.7.4 as well as 2.8.0; both running on macOS for MK3S+ MMU3
For those who didn't open the linked issue: the extrusion in the air is in fact NOT a bug, it is a misrepresented part of the tip forming procedure (ramming), where a short length of filament is extruded before the filament is removed from the nozzle completely. It might not even come out of the nozzle, despite being shown on the preview.
Description of the bug
In certain situations, such as creating "label" style prints, the final purge of the filament on the wipe tower is in mid-air. I presume this is done to create the proper tip for the filament, however it leaves a string of filament that hangs to nozzle or falls onto or behind plate.
It's repeatable, and consistent.
Project file & How to reproduce
ZipperPulls.3mf.zip
Using any profile with wipe tower and a label style print, it is easily reproduced. By label style print, I mean a 2 color print with 1 color only being used for the first few layers (2-4) while rest of print is single color and thus no wipe tower gets built. Turning on "no sparse layers" does not change outcome.
