<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>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 <a href="https://core.trac.wordpress.org/changeset/54155">[54155]</a>, 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`.
