I have a Gutenberg Block that fetches posts from a custom post type.
The custom post type does have a custom status registered.

The code in the block look something like this:

const POST_TYPE = 'my-custom-post-type';

// Get custom post type pages.
const childPages = useSelect((select) =>
  select('core').getEntityRecords('postType', POST_TYPE)
);

// childPages will look like this
// (only relevant keys kept)
// "status" is always "private"
// and we need to check "custom_status"
// to get the real status of the post.
[
  {
    "id": 123,
    "type": "my-custom-post-type",
    "status": "private",
    "custom_status": "publish"
  },
  {
	  // ...second post and so on
  },
]

I see that a check is in place to

Always trick the Block Editor so that is uses the "Update" major action button.

But it seems like this check also is true when getting pages from a block because the referer value seems to be the same as for the edit post api call.

I have solved this by checking if custom_status exists and use that value with a fallback to status, but I guess this would be a problem for other third party blocks that does not have this check.
