### System information

### Issue description

So far I've found these ones:

But there are likely more like them. They are invalid, at least in the context I encountered them here (at the beginning of a regular line of script)

### Steps to reproduce

Type `Anchor` in the code editor.

### Minimal reproduction project

N/A
ERR_FAIL_COND(p_recursion_depth > COMPLETION_RECURSION_LIMIT);
	if (!p_parent_only) {
		bool outer = false;
		const GDScriptParser::ClassNode *clss = p_class;
		int classes_processed = 0;
		while (clss) {
			for (int i = 0; i < clss->members.size(); i++) {
				const int location = p_recursion_depth == 0 ? classes_processed : (p_recursion_depth | ScriptLanguage::LOCATION_PARENT_MASK);
				const GDScriptParser::ClassNode::Member &member = clss->members[i];
				ScriptLanguage::CodeCompletionOption option;
				switch (member.type) {
					case GDScriptParser::ClassNode::Member::VARIABLE:
						if (p_only_functions || outer || (p_static && !member.variable->is_static)) {
