It looks simmilar to #48436 , but it started happening to every code completion and I have absolutely no clue how it happened.

It happened after I moved(using shift+arrow keys to select, tab to indent and alt+arrow keys to move down)  the three dicts in the picture to within the function and added the dict 4.

### Steps to reproduce

Here's roughly what I did 
(might be slightly inaccurate, I was basically messing around to try and see the scope of $77725 when it happened)

1) create an empty script
2) declare a couple of dictionaries
3) declare a function
4) try out code completion within the function
5) create a lambda within the function and try 4) again
6) move the dictionaries' declaration within the function using keyboard shortcuts and try 4)

accept_event();

			update_code_completion = true;
		} else {
			update_code_completion = (allow_unicode_handling && k->get_unicode() >= 32);
		}
		if (!update_code_completion) {
			cancel_code_completion();
		}
	}
	
	if (!code_hint.is_empty() && k->is_action("ui_cancel", true)) {
		set_code_hint("");
		accept_event();
		return;
	}
	if (allow_unicode_handling && k->get_unicode() == ')') {
		set_code_hint("");
	}
	
	if (k->is_action("ui_text_indent", true)) {
		do_indent();
		accept_event();
		return;
	}
	if (k->is_action("ui_text_dedent", true)) {
		unindent_lines();
		accept_event();
