Comment (by manfcarlo):

 The functions are definitely run twice, as it was determined to be the
 cause of the bug with the chessboard plugin as reported in #54614. I'm
 sure the opener of this issue would not have opened it if they had not
 verified that the functions run twice.

 Given the bugs it causes, using `the_content` filter is not an option.

 Additionally, the query loop block allows the post content of one post to
 be embedded within the post content of another post.

 The solution I propose is to move certain functions (`wptexturize`,
 `do_shortcode` and possibly others) out of `the_content` filter and into
 the block callback of certain blocks (paragraph block, classic block,
 heading block etc.) This will prevent them from ever being run twice on
 the same content.
