Since EAP8.0 revert functionality seems to have changed from "revert this update" to "revert to this update". Since then UI doesn't reflect this change. After aplying single update, revert button is only shown for this change:

Trying to revert fails with message: "PRSP00268: The revision fooo is the state of the current installation. Reverting to the same state is not a valid operation.

As a consequence revert button shouldn't be present for latest change, but for the previous ones.
