I wonder if Hyperkitty is able to leverage some other method to combine the thread correctly in this case?

There is no way to display a thread without threading information (in In-Reply-To: or References: headers). One can try to match by Subject and/or Date, but that is a heuristic bound to fail.

The "correct" way would be to fix the client that is erroneously [1] missing or deleting threading headers.
