WP_Terms_List_Table doesn't call sanitize_term() on display

[scribu]

Steps to reproduce:

Add this filter:

add_filter( 'category_slug', function() {
  return 'filtered';
} );

and go to edit-tags.php?taxonomy=category

[scribu]

For the slug in particular, there's 'editable_slug', which doesn't pass the taxonomy.

Also, that still leaves out all the other fields, like 'name', 'description' etc.

In 28360:

In WP_Terms_List_Table::single_row(), call sanitize_term() on the passed term ($tag).
