There seems to be a quality of life improvement that was removed in a recent patch.
If you trigger Twilight Falls while Wormhole is active and try to wormhole back it quickly triggers your next blink as soon as you wormhole back. This is probably caused by quick consecutive presses. It seems recently I end up burning my blinks all the time when I pick the level 20 talent, I think there was a safety margin before, but even a short gap should be allowed to stop the blink from triggering twice, much like you added to the VP cancel, although it doesn’t have to be as long.
