"wp_kses_post" stripping player gallery thumbnail images "srcset" and "sizes" attributes

[danis039]

The code echo wp_kses_post( $gallery ); in line 204 of player-gallery.php is removing the srcset and sizes attribute from gallery thumbnails, which disables WordPress's functionality of displaying the most appropriate image to the user's screen resolution/DPI. The usage of wp_kses_post here also removes some inline styles applied to the thumbnail, such as transform or transition. Is there a better alternative to using wp_kses_post here?
