Comment (by Bernhard Reiter):

 In [changeset:"54671" 54671]:
 {{{
 #!CommitTicketReference repository="" revision="54671"
 Blocks: Allow arrays for deprecated asset types in block registration.

 In `register_block_type`, continue to allow passing arrays as the
 `editor_script`, `script`, `view_script`, `editor_style`, and `style`
 arguments. Note that those fields were soft-deprecated in favor of their
 `_handles` counterparts in [54155], which would allow specifying multiple
 items. At the same time, the deprecated fields were limited to `string` or
 `null`.

 However, this broke existing code that passed an array as one of those
 arguments. For backwards compatibility, this change thus restores the
 previous behavior. It is implemented in `WP_Block_Type` as a pair of
 `__get()` and `__set()` methods that wrap around the corresponding
 `_handles` members, which are arrays of strings.

 It also affects the REST API endpoint for block types. The latter’s schema
 has never allowed for anything other than `string` or `null` for any of
 those fields. For this reason, it now returns the first element of the
 array stored in the corresponding `_handles` member in `WP_Block_Type`.

 Follow-up [54155].

 Merges [54670] to the 6.1 branch.
 Fixes #56707.
