### 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
for (const PropertyInfo &E : pinfo) {

							int location = p_recursion_depth + _get_property_location(type, E.name);
							ScriptLanguage::CodeCompletionOption option(E.name, ScriptLanguage::CODE_COMPLETION_KIND_MEMBER, location);
							r_result.insert(option.display, option);
						}
						List<MethodInfo> signals;
						ClassDB::get_signal_list(type, &signals);
