Preloaded enums do not automatically update to latest version

[ghost]

Godot version:

b550f93

OS/device including version:

Linux

Issue description:

Consider the following situation:

#scriptA.gd
enum MyEnum{
    ValueA,
    ValueB
}
...
#scriptB.gd
const ScriptA := preload("res://scriptA.gd")
export(ScriptA.MyEnum) var myEnum := 0

Everything is fine so far; your enum will appear in the inspector, and you can assign it to ValueA and ValueB.

However, you modify your enum later:

enum MyEnum{
    ValueA,
    ValueB,
    ValueC
}

myEnum can still only be assigned to ValueA or ValueB, ValueC does not appear. To trigger it to update, you must do any of the following:

1. Comment out the line that preloads, save, then uncomment, and save
2. Comment out the export, save, then uncomment, and save
3. Restart the editor

Ideally, saving the enum would trigger a reload for anything referencing it.

I assumed this was the case for anything that has been preloaded, but I tried it with a custom resource, and it seemed to show the updated version.

Confirmed in 99640ac.

For me at least, I only need to comment out the preloading line, save, and then remove the comment and it seems to trigger the refresh.

Still valid in 3.2.2

For me the enum didn't appear in the inspector until I added another export variable, which refreshed the inspector. Same with updating the enum values. What's weird, reloading scene doesn't help.

Still an issue in Godot 4.0b2

Still an issue in v4.0.beta13.official [caacade].

This is still useful in 3.5, just adding a new export var (then deleting if you want to) refreshes the preloaded enum.

Still seems to be an issue in 4.2 beta 5.
Not personally experienced enough with the Engine code to even know where to begin looking at solving this issue though.
