 A PR to track the backporting of https://github.com/WordPress/wordpress-
 develop/pull/7697


 The Gutenberg PR fixes an omission in the theme json merge logic where
 top-level background image objects are not replaced, rather they are
 merged, which was the state of affairs before
 https://github.com/WordPress/gutenberg/pull/64128

 Blocks are already catered for via `::get_block_nodes()`.
