Comment (by costdev):

 Looking into this more, it appears that when using a block theme,
 `do_shortcode()` is hooked to `the_content` twice. The first run renders a
 literal `[test]`, and the second run evaluates it.

 Adding this to the top of `do_shortcode()` shows that when limited to only
 one run on `the_content`, the shortcode is correctly escaped:

 {{{#!php
 <?php
 if ( doing_filter( 'the_content' ) && wp_get_theme()->is_block_theme() ) {
         static $did_block_theme_the_content = false;

         if ( $did_block_theme_the_content ) {
                 return $content;
         }

         $did_block_theme_the_content = true;
 }
 }}}
