Lunar Assualt's Built in Movement Stops if you have too High Attack Speed

Lunar Assualt has a built in movement component when you put your cursor away from your character.

However, if you have sufficient attack speed then this no longer functions.

I'm not sure what the exact threshold is but when I get it down to 0.27s attack time (3.68aps) it will no longer do the movement or movement animation. It's as if it doesn't have time to do the walking animation so doesn't.

At 0.3s attack time (3.33aps) it still functions.

It would be nice to have it back.
