Bug: wp_check_filetype_and_ext returns type and ext as false for font files

[madhudollu]

the function wp_check_filetype_and_ext returns both type and ext as false for font files (.ttf, .woff, .woff2 etc..)

This is because the $real_mime for the font files is application/octet-stream and the following condition has no check for font mimes. (font/ttf, font/woff)

// file: src/wp-includes/functions.php
// line: 3184

if ( in_array( $real_mime, $nonspecific_types, true ) ) {
  if ( ! in_array( substr( $type, 0, strcspn( $type, '/' ) ), array( 'application', 'video', 'audio' ), true ) ) {
    $type = false;
    $ext  = false;
  }
}
