Comment:

 See #46133 for necessary context here. @azaozz wrote a patch that has an
 exception for columns blocks, but this solution needs to be expanded to
 cover all core and non-core group blocks. This is especially important now
 that Gutenberg is adding different kinds of group blocks e.g. Group,
 Cover, Media & Text.

 > Yeah, thinking we will need to keep enhancing the way we auto-generate
 excerpts for posts and include all blocks that may have relevant text.
 >
 > The challenge is that we only want "static text" and need to exclude
 dynamic blocks as they may cause infinite loop if trying to generate an
 excerpt, and in most cases they are not particularly relevant to the rest
 of the post.
 >
 > Ideally we should parse all "text containing blocks" regardless if they
 are wrapped in "container" blocks. The current patch only looks one level
 deep in all whitelisted blocks, and has an exception for core/columns
 where it looks inside each column. This can be enhanced and perhaps can be
 done better. Planning to look at it again for 5.3.
