LPE envelope / perspective - freeze and sometimes crash dragging nodes together

Steps to reproduce:

  • open Inkscape
  • create 2 rectangles
  • group them
  • open LPE dialog and keep open (not sure if necessary to keep open)
  • apply LPE envelope to this group
  • check mirror movements in horizontal
  • drag nodes over other part of the cage

What happened?

  • unrecoverable freeze
    • Seems to loop on trying to update the LPE.
  • occasional crash (backtrace from comments indicates crash is same as inkscape#1415 , but have not been able to retrieve a backtrace in Windows)

What should have happened?

  • No freeze
  • No crash

Version Info:

- Inkscape Version: 1.0.1
- Operating System: win 10
