Start From Here with OverCut has issue

I’m doing some testing for plasma use case of LB and noticed errant move with Spindle Enabled (M3). I narrowed it down to this condition -

  1. using Start From Here feature
  2. using OverCut feature
    Problem: at end of shape cut, the cutter moves with spindle enabled (M3 in my case) to SFH starting node + Overcut amount.

I happen to be using GRBL-M3 mode since it’s most compatible with plasma torch trigger on/off state and movements, but I believe the issue also occurs in GRBL (M4) mode.
Simple test case posted here.

Is this a bug or did I code something wrong ?
