Drag & Drop intellisense with inferred type not working

[Dharmang92]

Tested versions

• Reproducible in: 4.2.1 Stable
• Testing working functionality in: 4.2 Stable and 4.1 Stable

System information

Windows 11 - Godot v4.2.1-stable - Vulkan (Forward+)

Issue description

I have a timer as shown in the attached image. When I tried to drag the timer to the script and use the dot notation to autocomplete the in-built functions of the Timer class, I didn't get suggestions.

While in v4.1 opening the same project gave intellisense.

Steps to reproduce

1. Create a Timer
2. Drag and drop in the gdscript editor.
3. Try to invoke the start method.

Tested in v4.2 stable in which it is working fine. There seems to be an issue between 4.2.1 and 4.2.
