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)

	ERR_FAIL_INDEX_V(p_line, get_line_count(), false);
	if (!line_folding_enabled) {
		return false;
	}
	if (p_line + 1 >= get_line_count() || get_line(p_line).strip_edges().size() == 0) {
		return false;
	}
	if (_is_line_hidden(p_line) || is_line_folded(p_line)) {
		return false;
	}
	
	if (is_line_code_region_end(p_line)) {
		return false;
	}
	if (is_line_code_region_start(p_line)) {
		int region_level = 0;
		
		for (int next_line = p_line + 1; next_line < get_line_count(); next_line++) {
			if (is_line_code_region_end(next_line)) {
				region_level -= 1;
				if (region_level == -1) {
					return true;
				}
			}
