### 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.
