Drowning Orbs in Mirages can silence the player, dooming the player with no mitigation

I'm normally able to use Frostblink or a similar skill to escape being snared by a Drowning Orb in an Originator map, however, when I get snared by one in a Mirage, the orb prevents the use of movement skills. This insures the death of the player with no possibility of escape.

Bug ID #1,619,339,292. It's possible that it's a bug to this specific map, but I've never seen this before.
