Prefabs with "Flags" enum properties result in "IndexOutOfRangeException" when trying to commit/revert

Unity: Serialization

Won't Fix

6.0.X

This is fixed in 6000.1 and higher, but is a significant change that is currently considered too risky to bring back to this version.

Reproduction steps:
1. Open the attached “IN-104297_PBGrowDeletionIssue.zip“ project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Select the “TestObject“ Prefab GameObject in the Hierarchy
4. Make sure “Flag vals“ field is set to “A,B“
5. Right-click on the “Flag vals“ label

Expected result: Context menu shows up
Actual result: IndexOutOfRangeException is thrown

Reproducible with: 2023.2.13f1, 2023.2.20f1, 6000.0.50f1, 6000.1.0b13
