Scarf Seam is incompatible with Z hop on slope and spiral #7380

The reason for that is this commit |

... though the reason for the blob seems to be something else since it still does it after me having restored the previous z-hop behavior and verified in the slicer preview before printing. |
Avoid collisions with previous extrusions in the same layer when moving Z down in an XYZ move. This happens for example when starting a scarf joint after another perimeter was already printed. Fixes #7191 Co-authored-by: SoftFever <[email protected]>

I noticed this issue with scarf seams a while back, but I didn't realise it was also because of z-hop until today.. I've been losing my mind over issues with "flakes" on walls and parts getting knocked over for months, and the only advice I could get online was "dry your filament" which I already knew wasn't the issue. Glad I've finally found the cause, though naturally, right after I've started turning off scarf seams and redrawing all my seams Photos of the "flakes": https://imgur.com/a/YvKhJuV Other than that, scarf seams seem to perform the same as before for me. I haven't noticed the aforementioned blob |
Is there an existing issue for this problem?

How to reproduce
Having SCARF SEAM and Z hop enabled on slope or spiral.
On slope and spiral z hop: Extruder retract, travel to next position, makes z hop in place, go down, print...

Actual results
Currently, except in normal Z-hop, the pieces end up with blobs on the perimeter because the travel moves are done without Z-hop
