### Godot version

4.0.2

### System information

Windows 11

### Issue description

Double clicking on `$MyNode` in the script editor will select the whole name including the "$".

But double clicking on `%MyNode` (unique name) will select the name but will not include the "%".

Dragging a node from the scene tree into the script editor brings up the property/method hint list, even though a "." has not been typed. Pressing enter appends "new()" even though this makes no sense as there is no period so it is just appending it directly to the node name: `$MyNodenew()`


### Steps to reproduce

Type `%MyNode` in a script and double click on it.

Type `@onready var x =` in a script, drag a node from the scene tree, then press enter.
