Related issues: #68475,  #73167.
I tried apply #68311, #69473 and #73196. It don't helps.
The `Ctrl+LMB` works right for all cases.

### Minimal reproduction project

Example from  #68475.

	ERR_FAIL_INDEX_V(p_level, _debug_call_stack_pos, nullptr);
	int l = _debug_call_stack_pos - p_level - 1;
	ScriptInstance *instance = _call_stack[l].instance;
	return instance;
}
void GDScriptLanguage::debug_get_globals(List<String> *p_globals, List<Variant> *p_values, int p_max_subitems, int p_max_depth) {
	const HashMap<StringName, int> &name_idx = GDScriptLanguage::get_singleton()->get_global_map();
	const Variant *gl_array = GDScriptLanguage::get_singleton()->get_global_array();
	List<Pair<String, Variant>> cinfo;
	get_public_constants(&cinfo);
	for (const KeyValue<StringName, int> &E : name_idx) {
