This is a regression. Tested in //UE5/Release-5.1 CL20979098

Variable can't be set by the Pick Actor From Scene eye dropper if that actor's name starts with an underscore "_".

1. Create a new project
2. Create and save a new Blueprint Actor then name it _Test
3. Place this Actor in the scene
4. Create another Blueprint Actor then open it
   1. Add a new Variable of type _Test named TestRef
   2. Enable Instance Editable and Expose on Spawn for this variable
   3. Compile, save, and close the Blueprint
5. Place this Actor in the scene and keep it selected
6. In the Details Panel find the TestRef variable
7. Use the Pick Actor From Scene eye dropper tool to select the _Test actor that is in the scene

Expected Results:
The _Test actor that is in the scene is now the reference for the variable.

Actual Results:
The variable remains set to None.
