Issue description

While I'm typing functional code, the console is getting flooded with error reports:

The code functions as expected (and looks fully in order when checked using various "print"s) once the game is launched.

Steps to reproduce

Add a vertical container to a project.
Add two buttons or so to the container.
Add a script to the container (in my case I'm using an inbuilt script if it matters).
Paste this into the script:

func _ready():
	menu_buttons = get_children()
	for B in menu_buttons:
		B.pressed.connect(button_trigger)
		
	if menu_buttons.size() > 0 :
		menu_buttons[0].grab_focus()

func button_trigger():
	pass

(If you launch the project it should work.)

In the script, erase the last line and start typing it back in.
When you type past "[0]." part, a new error will be reported for every keypress and the console will get flooded.

Minimal reproduction project (MRP)

Buttons and a container.
