 This commit seems to have broken the `use_block_editor_for_post_type`
 filter in WP >= 5.9.

 https://github.com/WordPress/WordPress/blob/5.9.2/wp-includes/default-
 filters.php#L592

 Is part of default-filters:
 {{{#!php
 <?php
 add_action( 'use_block_editor_for_post_type',
 '_disable_block_editor_for_navigation_post_type', 10, 2 );

 }}}

 But that function `_disable_block_editor_for_navigation_post_type` is only
 registered if user is on admin screen.


 So, if you're on homepage and try to: `apply_filters(
 'use_block_editor_for_post_type', true, 'post' )` it will return null and
 throw a warning:

 {{{#!php
 call_user_func_array() expects parameter 1 to be a valid callback,
 function '_disable_block_editor_for_navigation_post_type' not found or
 invalid function name
 }}}
