Changeset 51894 for trunk/src/wp-includes/class-wp-block.php

Timestamp:

Message:

Apply the pre_render_block, render_block_data, and render_block_context filters when rendering inner/nested blocks. Introdices another param to these filters: $parent_block that is the "parent" WP_Block instance for nested blocks and null for top level blocks. Adds unit tests for the filters.

Props noisysocks, gaambo, azaozz.
Fixes #51612.
