Comment (by azaozz):

 In 46133.3.diff:
 - Add a (non-filterable) `$allowed_inner_blocks` list. Same as the default
 `$allowed_blocks` except `core/columns`.
 - When rendering the allowed blocks, exclude blocks that have non-
 whitelisted or nested inner blocks.
 - Add a helper function to render whitelisted blocks from inside the
 columns block.
 - Fix the tests to match the output from get_the_excerpt() (has some
 "unusual" left over white space).
