Sketchup::Materials#[] Fails to Identify Renamed Materials After Undo

[voqhai]

Identified an issue with the method Sketchup::Materials#[] where it fails to locate a material if the material has been renamed and cannot be found by its name after an undo operation.

Steps to Reproduce:

1. Rename a material using the SketchUp user interface or through the API.
2. Attempt to locate the material with its new name using Sketchup::Materials#[].
3. Perform an undo operation.
4. Attempt to locate the material again using its original or new name with Sketchup::Materials#

Environment: SketchUp Version: SketchUp 23.1 Operating System: MacOS

I can reproduce this issue on Windows too.
