attachment_updated live events are not firing

[Seto]

Hi,

I am testing live events and I am successfully receiving events for attachment_created and attachment_deleted. The attachment_updated event is also working when file name or content is updated. However, attachment_updated is not being fired when the visibility of the file is updated. For example, locking, unpublishing, lock & unlock at specific dates. 

Do these changes fire another event or is this not supported? 

Delivery method: HTTP

Subscription: attachment.*

Thank you
