Pyke W Ghostwater Dive not applying bonus MS.

Upon returning from the laboratory, I have discovered something a little obscure but a very serious issue looking ahead at how pyke should be played(imo). When using Gargoyle Stoneplate on Pyke, the bonus active properly increases the % of bonus decaying movement speed in the tooltip, but the stat does not actually correctly apply.

The devs should know what I mean but basically, when you activate gargoyle stoneplate, your health increases which increases your ad, which makes your w grant more movement speed when you cast it(his w scales off of bonus ad). However, if you watch the movement speed stat, it clearly does not correctly apply this from Stoneplate.

To recreate this, simply hit your w and watch what the movement speed starts at, keep that value in mind. Then, use the gargoyle stoneplate active and use the w right after, and observe that the tool tip shows the correct bonus, but the movement speed stat remains unchanged from the previous value we got.
