 A shortcode block that evaluates to nothing renders as a space in the
 HTML.

 I've noticed it while using an [acf] shortcode referencing an empty field,
 but it also happens with an empty [audio] core shortcode.

 This makes styling with CSS cumbersome. For example, the :empty selector
 can't be used.

 When I remove the shortcode block, leaving the column block completely
 empty, the redundant space isn't being rendered (so it isn't a browser
 issue).

 I've tried to reverse-engineer it really hard, even trying to catch the
 HTML at the last minute in the get_the_block_template_html() function, but
 I couldn't find the culprit spaces.
