Deprecated warning Link Manager

Hi,

I still have the native Link Manager enabled and there are some deprecated warnings at the Add Link page, regarding the editor switch meta box. Example:

Deprecated: strstr(): Passing null to parameter #1 ($haystack) of type string is deprecated in my-domain\wp-includes\functions.php on line 1154

As the Link Manager does not support the Block Editor, adding an extra condition to file classic-editor.php will solve this and hide the meta box on the Add Link page.

$current_screen = get_current_screen();

if ( ! $editors['block_editor'] || ! $editors['classic_editor'] || ( $current_screen !== 'link' ) ) {
