Demon hunter vault issue

in dh impale, multi or rapid
only in ptr (the last 3 seasons, in ptr servers. this error does not apply to production diablo 3 and is not a rubber banding issue)

when playing and holding shift down and vaulting more than once I vault 2 times. normally back to where i was or in a random direction.

while not holding shift this issue is less but still happens
