Considerable delay when changing 2D view -> editor script (with open doc)

### Tested versions

v4.3.dev5.official [89f70e98d]

### System information

w10 64

### Issue description

When I switch between 2d -> script editor and the script editor is showing the godot documentation, there is a considerable delay.
This delay does not occur if what is displayed in the script editor is a script.

### Steps to reproduce

Show documentation in script editor and toggle between 2d -> script editor

### Minimal reproduction project (MRP)

...

Start by reproducing the delay with Godot documentation open in the script editor, then compare switching from the 2D view to the script editor with a script displayed. Use the supplied video and tested version as the baseline. Done means the transition no longer has the considerable delay when documentation is open.
