### Issue description

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.

### Steps to reproduce

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.
int idx = _get_auto_brace_pair_open_at_pos(cl, cc);
			if (idx != -1) {
				prev_column = cc - auto_brace_completion_pairs[idx].open_key.length();
				if (_get_auto_brace_pair_close_at_pos(cl, cc) == idx) {
					remove_text(prev_line, prev_column, cl, cc + auto_brace_completion_pairs[idx].close_key.length());
				} else {
					remove_text(prev_line, prev_column, cl, cc);
				}
				set_caret_line(prev_line, false, true, 0, i);
				set_caret_column(prev_column, i == 0, i);
				adjust_carets_after_edit(i, prev_line, prev_column, cl, cc + auto_brace_completion_pairs[idx].close_key.length());
				continue;
			}
		}
		
		if (indent_using_spaces && cc != 0) {
			if (get_first_non_whitespace_column(cl) >= cc) {
				prev_column = cc - _calculate_spaces_till_next_left_indent(cc);
				prev_line = cl;
			}
		}
		remove_text(prev_line, prev_column, cl, cc);
		set_caret_line(prev_line, false, true, 0, i);
		set_caret_column(prev_column, i == 0, i);
		adjust_carets_after_edit(i, prev_line, prev_column, cl, cc);
