Have the Slowness Effect be as effective while Running and Jumping at once

The Slowness Potion can be useful on players, if they are not running and jumping at the same time. If a player is running and jumping at the same time while under the Slowness Effect, they will move faster than just sprinting on the ground. If the Slowness Effect made players that are sprinting and jumping at the same time move as slow as if they were only sprinting and not jumping, then The Potion of Slowness would be much more reliable to use on players since they would not be able to escape as easily in PvP.
