Comment:

 In [changeset:"51382" 51382]:
 {{{
 #!CommitTicketReference repository="" revision="51382"
 Posts: Prevent an empty excerpt when groups and nested column blocks are
 present.

 This improves the logic within excerpt_remove_blocks() to better handle
 innerBlocks. This prevents an empty excerpt from being returned when
 core/columns, core/column, and core/group blocks are present.

 This issue has been surfaced in the Query Loop block, where excerpts can
 be set to display.

 This introduces the excerpt_allowed_wrapper_blocks filter for controlling
 which blocks should be considered wrapper blocks.

 Wrapper blocks and their nested contents are not stripped by
 excerpt_remove_blocks(), allowing their contents to appear in generated
 excerpts.

 Backports [51348], [51375], [51378], and [51379] to the 5.8 branch.

 Fixes #53604.
 Props aristath, jorbin, SergeyBiryukov, desrosj.
 Unprops jorbin.
