Images not displaying when vault is stored on network drive

From this post: Image viewing not working I see there is a known issue for images not displaying when a vault is stored on a network drive. This post suggests this was going to be solved in version 14, but since 14.6 is out and the issue is not solved, as witnessed by my current setup, it there an update when this will be resolved? Is there a link to the bug ticket? BTW: this used to work just fine.
