Library Back Icon Not Working In Webradio Folders

[R101G]

@rern
I have just tried the 20250809 update to see if the oversized image problem is fixed, and found that the back arrow icon does not work in webradio folders.

Working after I did an Update today .

After an UPDATE at 250817 07:30 UTC+2 the back arrow works for one-level webradio directories.
But there is a regression in two-level subtrees, the folders are empty.
We had this situation several times in the past, e.g. #1786

After the next UPDATE at 250817 14:01 UTC+2 the regression has been fixed.
