when I try to set an embeds_many relation to an empty array, it removes the embedded relation from the document and it's not tracking the changes anymore, which is not desired, as there was a change on the document. Also this causes inconsistencies in the data as the data is lost and there is no way to know that it was unset. 

I read through some closed issues and apparently this is somehow a known behaviour, is there any way to prevent this from happening ? 

Some background: 

We are tracking the changes on objects and it's important to know if there was a change on the associations as well.
