Post created with patterns - missing excerpt

[MarkS99]

When posts are setup using some of the stock patterns, no excerpt is available for the post on blog page.
Seems to affect the following 'stock' patterns:
Columns: Two Columns, Two Columns with images, Three columns with buttons.
Text: Heading & Text, and Quote
Headers: Large Header with heading, Large header with a heading and a button.

Tested on custom theme, and also clean vanilla WP5.6 install, using Twenty Twenty-One

Just to note, I have also tested editing and replacing default text - excerpt is still not available.

Hello @MarkS99! Thank you for reporting this. We reviewed the ticket during one of our [recent triage sessions]​https://wordpress.slack.com/archives/C02RQBWTW/p1622524033126700. Based on the feedback from the team we have modified the information on the ticket.

@mamaduka also shared [his feedback]​https://wordpress.slack.com/archives/C02RQBWTW/p1622524926134400 referencing [excerpt_remove_blocks]​https://developer.wordpress.org/reference/functions/excerpt_remove_blocks/. So columns should be removed. TT1 displayed excerpt on homepage by default and we could see them removed. There's also excerpt_allowed_blocks filter, so this behavior can be altered. So if we're using a custom theme with inner blocks, then the inner blocks will need to be added via a filter in that function. When we wrapped the column pattern in a group the excerpt was gone.
