Freeze when you start making a thread but edit the original message with the thread starter open

Reproduction steps

Send a message in a text channel you have thread creation permissions in
Click the button to create a thread
Don't start the thread, just keep that panel open.
Go back to the original message and edit it instead

Expected behaviour

You should be able to edit the message even with the thread open

Actual behaviour

As soon as you press enter to submit the edited OP for the thread, the entire fluxer client freezes (and in my case, running Fedora 44 + KDE Plasma, with Fluxer installed via rpm, also freezes plasmashell). The only recovery for me was to run:

pkill -9 fluxer-canary
pkill -9 plasmashell

In a browser, this just locks up the browser tab completely. I'm kind of curious how this manifests on other platforms. Hopefully not as bad.
