KDialog not displaying thumbnails/previews for remote share

SUMMARY
When attempting to view the contents of a remote SMB share within KDialog, thumbnail/side-panel previews are not being displayed. Dolphin displays thumbnails/previews for these directories without issue. Moreover, thumbnails/previews for local directories are generated and displayed in KDialog without issue.

STEPS TO REPRODUCE
1. Mount an SMB network share (the options I'm using are uid=1000,gid=1000,vers=3.0)
2. Ensure that "Show Preview" and "Show Preview Panel" are enabled
3. Navigate to the share via an Open/Save KDialog window

OBSERVED RESULT
Thumbnails and side-panel previews are not being displayed.

EXPECTED RESULT
When the above options are enabled, thumbnails and side-panel previews should be displayed. 

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.17.1-zen1-1-zen (64-bit), Arch Linux
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3

ADDITIONAL INFORMATION
The regression appears to have occurred in 5.91.0. Upon downgrading to kio 5.90.0, thumbnails and previews are generated/displayed properly again.
