Block reference content disappears when collection-level update permission is false

[rilrom]

Describe the Bug

When a project is using blockReferences and collection-level update permissions are set to false, the block content disappears instead of being read-only.

This issue does not occur when using blocks.

I've narrowed it down to the below code in the BlockRow component:

if (permissions === true) {
    blockPermissions = true
  } else {
    const permissionsBlockSpecific = permissions?.blocks?.[block.slug]
    if (permissionsBlockSpecific === true) {
      blockPermissions = true
    } else {
      blockPermissions = permissionsBlockSpecific?.fields
    }
  }

When using blocks, permissions?.blocks is { title: { fields: [Object], create: true, read: true } } however when using blockReferences, permissions?.blocks is true, which leaves blockPermissions set to undefined.

Reproduction Steps

1. Create a new post with a title block.
2. Uncomment update: () => false for the posts collection.

When reading the documentation, I see this mentioned under block references:

"Access control for blocks referenced in the blockReferences are run only once - data from the collection will not be available in the block's access control."

This makes it sound like what I've raised here is intended?
