Make Engine.get_main_loop() valid before _static_init()

[CsloudX]

Describe the project you are working on

NoGame App

Describe the problem or limitation you are having in your project

I'm so love Godot4's static variable and I want design a Helper class for auto set some information for Engine.get_main_loop().root, but failed. In _static_init function, Engine.get_main_loop() return null.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

IMO, it should alway can get Engine.get_main_loop() and Engine.get_main_loop().root.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

If this enhancement will not be used often, can it be worked around with a few lines of script?

/

Is there a reason why this should be core and not an add-on in the asset library?

I think it's probably bad practice to use _static_init() like this. Even if we fix the bug that the engine is not fully initialized by the time user code is executed, you still have little control over the order in which classes are loaded and their static constructors are called. In my opinion, _static_init() should only be used for more complex initialization of static variables.

No, I'm only care Engine.get_main_loop() and Engine.get_main_loop().root was valid in _static_init(). not care other static constructors

Hello, I'm test again. And I found in 4.1, it return null, in 4.2, it return a valid object.
So, was this a bug and was fixed 4.2?
