Support custom sources (like acf/field) in the Attributes Panel UI

The new Attributes Panel introduced in WordPress 6.7 is great for visually binding block attributes to data sources like custom fields.

But currently, it only works with the default core/post-meta source (via register_post_meta()), and does not support custom sources like acf/field.

What’s the issue?
Even though acf/field bindings work perfectly via the code editor, they are not available in the UI. The panel doesn’t show up for those fields.

Example working code:

<!-- wp:paragraph {"metadata":{"bindings":{"content":{"source":"acf/field","args":{"key":"field_67ab390672809"}}}}} -->
<p></p>
<!-- /wp:paragraph -->

Request:
Please make the Attributes Panel support all valid sources registered via the Block Bindings API – not just core/post-meta. For example:

• Detect acf/field source
• Let users pick ACF fields in the panel UI
