Reproduction steps:
1. Open the attached project "CrashRepro"
2. Right-click any GameObject in the Hierarchy window > Modern UI pack > Buttons > Standart
3. Ctrl + d (duplicate) a few times (not necessary but seems to make it crash more consistently)
4. Ctrl + z (undo)
Expected result: Button creation is undone
Actual result: Editor crashes
