Certain moves that push enemies along with you (Hirazuki) can sometimes leave the user in places where they shouldn't be (like in a wall or floating, like in the case of the ledges in the Sea of Clouds).  
The conditions are fairly specific though.

To recreate this:

Target a heavy enemy (an enemy that cannot be pushed via normal means, like a Gold Beetle or a Wings of Fire) with Hirazuki while aiming directly at a wall (or ledge).  Since these enemies can't be moved normally, they'll be pushed out of the way with the user running forward still, but instead of stopping at a wall or obstruction, the user will instead pass through it for the full duration of the skill.  (Image provided... NOW it is.)

I'm admittedly going to be a bit sad to see this go, mostly because from a mechanical standpoint it's nice to run through small obstructions this way (and is why I initially believed it to be intentional in some cases), but then I noticed I was floating one day.  Very silly stuff.

I'm going to miss the Wile E. Coyote memes... o7

This should be corrected in 2.85e.
