Comment (by mw108):

 Same issue here as @joelmadigan - This new feature breaks NinjaForms when
 you have {{{img}}} tags in your fields.

 The "magic" happens in {{{wp-includes/media.php}}} in {{{function
 wp_filter_content_tags( ... )}}}:

 Forcing the {{{decoding="async"}}} attribute by using {{{preg_match_all}}}
 into all {{{img}}} tags is a bad solution. This has been discussed many
 times on StackOverflow: You should not parse HTML using regular
 expressions. Parse the DOM properly.
