Godot 4: Visual Script's variable hinting doesn't work

[archerallstars]

Godot version

v4.0.alpha3.official [256069e]

System information

Windows 11, Vulkan Clustered, Intel UHD Graphics 620 v30.0.101.1340

Issue description

Visual Script's variable hinting doesn't work, as shown in the screenshot below:

This is a regression from Godot 3.4. For example, if the users set a variable hint to Enum, then set the hint strings, the value(int) of the variable would be shown as the hint string accordingly, as shown in the screenshot as shown below:

I expect the variable hinting to work in Visual Script.

Steps to reproduce

1. Create a new variable as int type in Visual Script.
2. Change the Hint to Enum.
3. Add Hint Strings as much as you want. You won't see the value box change into the Hint String value.

I just noticed that hinting for the engine built-in property is working fine, for example, the rotation_order from Node3D class, as shown in the screenshot below:

But the user-created variable's property will not show the hinting, as shown in the screenshot below:

4.0 no longer has VisualScript.
