 {{{
 #!CommitTicketReference repository="" revision="59442"
 Editor: Avoid unnecessary array_merge in
 WP_Style_Engine::parse_block_styles().

 This adds an `! empty()` check for classnames and declarations to avoid
 calling array_merge() with an empty value.

 Props mukesh27, ramonopoly, aaronrobertshaw.
 Fixes #62317.
