 Hi,

 There is sourceURL= now in styles tags, that can not be disabled.

 {{{
 <style id='wp-img-auto-sizes-contain-inline-css'>
 img:is([sizes=auto i],[sizes^="auto," i]){contain-intrinsic-size:3000px
 1500px}
 /*# sourceURL=wp-img-auto-sizes-contain-inline-css */
 </style>
 }}}

 And there are all the block styles have these comments.

 {{{
 /*# sourceURL=wp-img-auto-sizes-contain-inline-css */
 }}}

 Since this is for developers purposes, can this be disabled with a help of
 condition SCRIPT_DEBUG https://developer.wordpress.org/advanced-
 administration/debug/debug-wordpress/#script_debug please to improve
 performance?

 These comments add additional kbs to a page.

 Kind regards
