Snapshot option missing for Zvol's in contextual menu on pools UI

I noticed this UI bug on both verions of the beta.  The snapshot option is missing from the contextual menu on the Storage Pools UI for zvol's however the option does exist at the dataset level.

I have attached screen shots from Freenas 11.3 to show that the option was there in the previous release and a screen shot from Turenas 12 beta2 showing the missing option.
