Clean Safari's history or restart MAC, all cannot resolve this issue

Safari 14 is obsolete, can you please confirm if this affects Safari 15.1 or newer? I don't quite understand the steps to reproduce, so it would help if you added detailed step by step repro. Also, could you please attach the crash log (should be visible in Console.app)?
