youknowriad f67cb7370e Editor: Prevent infinite loops when filtering the font library folder.
Changing the font library is something we expect hosts to perform.
It's important that we make this filter as seemless as possible.
This commit prevents a potential infinite loop caused by calling wp_get_upload_dir() within the font_dir filter.

Props mmaattiiaass, ironprogrammer, costdev, swissspidy.
Fixes #60652.
