SUMMARY
When using fish:// to connect to a remote file system in dolphin, selecting two files, then using context menu to "Compare files", kompare opens but no files are loaded to compare.

It works as exepected when on a local file system.  Also clicking on a file and oopening with kwrite, the file is loaded in kwrite and if changed saving that loaded file changes the file on the remote host.  So KIO seems to be working correctly.

Note that comparing remote files worked before the upgrade to KDE 6 (Fedora 39).

STEPS TO REPRODUCE
1.  Open Dolphin
2.  Enter fish://remote_host/etc in location bar
3.  Select two files
4.  Select "compare files" from context menu

OBSERVED RESULT
Kompare opens but both panels are empty.  I assume that is because the two files selected were not loaded from the remote host.

EXPECTED RESULT
Kompare should open the two selected files from the remote host.

No respnse to this so I altered the product.  It occurred to me that the issue may not be kompare, but is instead dolphin or even KIO.
