[Issue]: Group Movies in to Collections Display option Causes timeouts because of recursive isVisible checks

[jedthe3rd]

Please describe your bug

When "Group movies into collections is enabled" under Libraries > Displays it causes api timeouts because of recursive isVisible checks.

Most likely introduced here:
#8678
As it wasn't occurring in 10.8.z

I was able to pinpoint this issue by running my server data files on a dotnet run version of 10.9.z branch and then debugging to find the source of the thread causing the looping parental rating check.

Reproduction Steps

1. Install jellyfin and add a home videos and photos library with at least 4000 items that are divided in sub folders
2. Enable Group movies into collections display option
3. Wait for library to be scanned
4. Access library

Jellyfin Version

10.9.0

I meet an error about 504:
The API endpoint: Users/d88858318a2847c8a103484b9b8e88aa/Items/Latest?Limit=16&Fields=PrimaryImageAspectRatio%2CPath&ImageTypeLimit=1&EnableImageTypes=Primary%2CBackdrop%2CThumb&ParentId=772db055fe30a332896493a09158bb2c

The server is behind an Nginx Proxy Manager.

Is it the same as this bug?

Turn off group movies into collections in your library settings and if it is the same bug then it should stop happening.
