Witnessed in a recent game watched (Match ID unavailable). Bounty Hunter in Windwalk, threw a Shuriken at a Windrunner that had just initiated Windrun. The Shuriken particle appeared ahead of the Windrunner model, traveling at normal speed, moving in the same direction Windrunner was. After a second or so, the Shuriken particle 180'd and hit the Wind runner as intended.

The Shuriken particle did not originate from the Bounty hunter model, but from the WindRunner model.

Location: Radiant base.

Bounty Hunter: At bottom of stairs to mid base entrance.

Wind runner To the left of middle tower, windrunning to fountain. (path took her to the north side of the Ancient.)
