Dig Map - Stalker of the Endless Dunes stuck in Phase Run

Please see the YouTube video description for exact times the bug occurs. 3 Occurrences in the video.

When Enduring Cry (or perhaps any taunt?) is used during the Phase Run cast animation, the Stalker of the Endless Dunes becomes immobile, but still untargetable and invulnerable due to her Phase Run. This persists until you leave and reenter the arena.

Upon reentering the arena she will resume normal combat. However, she will move EXCEPTIONALLY fast for her Phase Run phase, (as noted in the video above), and will recast Phase Run immediately upon attacking the player.

I am out of Dig maps, so I could only test it on one set of portals, but the video linked above will show the bug occurring on 3 separate occasions, all of which involved me using Enduring Cry during her Phase Run cast animation.
