EditorLogic issues when rerooting a grabbed subsection to a surface mounted part.

[darthgently]

KSP 1.12.2, debian linux.  Quite a few mods.

I'm mod-clicking/copying a subsection of the craft, pressing "4" to reroute the subsection still held by the mouse curse, selecting a surface mounted dock port on the subsection as the new root part for the subection.  Up to this point all goes fine.  But when I pick up the re-rooted subsection by the root part (dock port) and attempt to attach it to a dock port on the main craft, the EditorLogic errors flow in the log, sometimes the subsection starts creating "trails" where copies of itself spread across the editor screen and sometimes the only way out of the loop of infinitely spawning copies is to reload the craft file.

My question is this: is re-rooting to a surface mounted part the soft ground here?  I want a way to avoid this problem.
