The "Lookup Symbol" button don't appears for custorm class names.
Related issues: #68475,  #73167.
I tried apply #68311, #69473 and #73196. It don't helps.
The `Ctrl+LMB` works right for all cases.

Right click to the `CustomClassA` symbol in the `custom_class_b.gd` anywhere. The `Lookup Symbol` button don't appears in the context menu.

### Minimal reproduction project

Example from  #68475.
r_type.type.builtin_type = Variant::DICTIONARY;
				found = true;
			} break;
			case GDScriptParser::Node::ARRAY: {
				
				const GDScriptParser::ArrayNode *an = static_cast<const GDScriptParser::ArrayNode *>(p_expression);
				Array a;
				bool full = true;
				a.resize(an->elements.size());
				for (int i = 0; i < an->elements.size(); i++) {
					GDScriptCompletionIdentifier value;
					if (_guess_expression_type(p_context, an->elements[i], value)) {
						if (value.type.is_constant) {
							a[i] = value.value;
						} else {
							full = false;
							break;
						}
					} else {
						full = false;
						break;
					}
				}
				if (full) {
					
					r_type.value = a;
				}
				r_type.type.type_source = GDScriptParser::DataType::ANNOTATED_EXPLICIT;
				r_type.type.kind = GDScriptParser::DataType::BUILTIN;
