 This is a follow-up to #64442.

 On a website with older theme [https://www.elmastudio.de/renkon-premium-
 fotografie-wordpress-theme/ Renkon] 1.0.9 from ElmaStudio the WordPress
 gallery shortcode causes layout issues after WordPress 7.0 update.

 Reason is the removal of gallery shortcode inline CSS by the theme which
 does not work any more due to missing `type` attribute in WordPress 7.0
 `$gallery_style` code:

 {{{
 /*-----------------------------------------------------------------------------------*/
 /* Remove inline styles printed when the gallery shortcode is used.
 /*-----------------------------------------------------------------------------------*/
 function renkon_remove_gallery_css( $css ) {
         return preg_replace( "#<style type=\"text/css\">(.*?)</style>#s",
 '', $css );
 }
 add_filter( 'gallery_style', 'renkon_remove_gallery_css' );
 }}}

 Out hotfix was updating the older theme code, so their filter works again.
