crash dereferencing ORIGIN_TRANSFORMS when both PCBNew's and FootprintEditor's properties inspectors are open

Description

footprint editor invoked from pcbnew on in-place footprint causes crash when exiting, if you have selected an item in footprint editor

Steps to reproduce

1. in pcbnew choose a footprint, select, and "Edit Footpint...."
2. in footprint editor, click on any item (pad, text, etc)
3. exit footprint editor ctrl-W
4. pcbnew/kicad crashes

This happened on my real project but also on this trivial testcase (select C1, Edit Footprint.... ,click an item, ctrl-W, crash):

99-kicad-7.0-testcase-jlcpcb-export.zip

Observations:

• Seems to happen 100% of the time
• exiting footprint editor without selecting an item does not trigger crash
• selecting any item in footprint editor is sufficient (I have tried pad, text)
• un-selecting item before exiting does not prevent crash
