Bug Description

Opening a file list URL from another user's personal space silently redirects to your own Personal root, even when the fileId in it is accessible to you.

Reproduction Steps

1. As user A, share folder R (with subfolder sub) with user B
2. As B, open A's URL /files/spaces/personal/<A>/R/sub?fileId=<id of sub>

Expected Outcome

The fileId gets resolved like /f/<id> and opens /files/spaces/share/R/sub. Without access, a not found message is shown.

Actual Outcome

B lands on their own Personal root without any message, the fileId is dropped. /f/<id of sub> works fine.
