Moonwalking Pantheon - Visual Bug

Found a small quite amusing Visual Bug that causes Pantheon to get directionally stuck in his walking animation for an extended period of time, entering a new animation such as AA or Spells doesn't cancel the bug. Steps to replicate are currently unknown though I can only assume it has to do with the interaction between Pantheon's E and any displacement CC as this bug has been seen before with Pantheon fighting Ahri.

If you have any more information please share it as I do want to figure out what exactly causes this little amusing Moonwalk
