Royal Decree bug or intentional?

Entangle used to be removed by attack buffs and was changed about a year ago:

• ENTANGLE: This is no longer removed by Attack buffs, in fact it now stops any Attack buffs applying while in effect.

This is a little unclear with the in-game text for Entangled, but at the end of the day it is working as intended.
