Comment (by azaozz):

 This is somewhat similar to #46133. Ideally the post content should be
 split on `<!--more-->` after the blocks have been parsed. As that's not
 possible, seems the only way to fix this is to treat the `<!-- wp:more ...
 -->` block same as the `<!--more-->` tag: split the post at that place and
 remove the tag and the block.

 Looking at 46471-2.diff, it seems to work properly (I know, parsing
 strings out of HTML with regex is...). Wondering if it would be a bit
 better to do a str_replace() for the block end delimiter. Makes the regex
 a tiny bit simpler and we need to run it only on the first part of the
 split post_content.
