23203	[PATCH] Simplify Way dialog can cause a deadlock	jim.walseth@…	team	"==== What steps will reproduce the problem?
1. Open the attached file ""SimplifyCrash.osm"" using JOSM.app on Mac (Ventura, 13.5.2)
2. Select the cluster of 5 buildings in the center (screenshot attached).
3. Use Shift+Y to launch simplification dialog. 

==== What is the expected result?
The dialog will 'preview' how many nodes will be removed. Clicking Simplify removes them.

==== What happens instead?
The dialog is unresponsive. I have to ""force quit"" JOSM.

==== Please provide any additional information below. Attach a screenshot if possible.
