This is a very creative use case. Unfortunately you've managed to trigger multiple known virtually unfixable issues. nAws such, this isn't feasible for us to fix in our code, sorry.

The best I can offer is a recommendation on how to proceed in the future: perform the conversion locally and then copy the output file to the remote server later--preferably after connecting to it in Dolphin which will use kio-fuse, rather than using a manual sshfs mount.
