Pinned block does not persist after page reload

Target: admin.company-details.block.render

Behavior: Pinning a block shows the toast “You pinned X for all staff”
but the block disappears after page reload. Tested on two separate
production deployments.

Expected: Block should persist across page reloads as documented.

@Alan_Catozzi This issue was supposed to be fixed yesterday, see this thread here: Admin block on company detail page won't stay pinned after refresh
