SUMMARY
right after navigating to an SFTP location, the Go -> Up menu item is not available when it should be.

STEPS TO REPRODUCE
1. in a fresh Dolphin window, navigate to an SFTP location by typing a URL in the address bar (in my case, "sftp://ahihi@10.0.0.3")
2. in the resulting directory (in my case "sftp://ahihi@10.0.0.3/home/ahihi"), try to go to the parent directory, either by selecting Go -> Up or pressing alt+up

OBSERVED RESULT
Go -> Up is greyed out, and alt+up does nothing. it is not possible to go to the parent directory.

if i first go into a subdirectory, then go back up, "Up" becomes available again.

EXPECTED RESULT
Go -> Up and the associated keyboard command should work in any non-root directory.
