Hot-reloading issue with specific child class of a generic class

[Nu99et]

When a class inherits from a generic class with itself as a type argument, FSR tries to hot reload but causes error due to the reference to original class name is missing.

For example, the class below will causes exception when modified inside play mode.

public partial class GameManager : MonoBehaviourSingleton<GameManager>

FSR: Error when updating files: 'GameManager.cs', FastScriptReload.Editor.Compilation.HotReloadCompilationException: Compiler failed to produce the assembly. Output: 'C:\Users\Nugget\AppData\Local\Temp\0fe7e28f1b734ebeb756f4db6ff4d726.SourceCodeCombined.cs(42,152): error CS0246: The type or namespace name 'GameManager' could not be found (are you missing a using directive or an assembly reference?)' ---> System.Exception: Compiler failed to produce the assembly. Output: 'C:\Users\Nugget\AppData\Local\Temp\0fe7e28f1b734ebeb756f4db6ff4d726.SourceCodeCombined.cs(42,152): error CS0246: The type or namespace name 'GameManager' could not be found (are you missing a using directive or an assembly reference?)'

Is it a known or unknown limitation, or a bug?
