 Since WP 5.6 there exsists
 {{{#!php
 <?php
 function clean_dirsize_cache( $path ){}
 }}}
 at [https://core.trac.wordpress.org/browser/branches/5.6/src/wp-
 includes/functions.php#L7725 functions.php:7725].
 There we have
 {{{#!php
 <?php
         while ( DIRECTORY_SEPARATOR !== $path && '.' !== $path && '..' !==
 $path ) {
                 $path = dirname( $path );
                 unset( $directory_cache[ $path ] );
         }
 }}}
 at [https://core.trac.wordpress.org/browser/branches/5.6/src/wp-
 includes/functions.php#L7735 functions.php:7735] which loops „forever“ if
 `$path` is something like `c:\dir\subdir` on Windows.
 {{{#!php
 <?php
 $path = dirname( $path );
 }}}
 returns the parent path in each step and gets „stuck“ at `c:\`.
