Jumping up a ledge from a pushable gets you stuck in your spinning frames

Just what the title says, I've attached a small example map just because I couldn't be bothered to record a gif of it.

Possibly related to this perhaps?: http://mb.srb2.org/showthread.php?t=38674

I can confirm that this has been a bug since 2.0 and perhaps earlier, I just never remembered to report it the numerous times I encountered it. It seems to occur whenever you "land on" a floor with a vertical speed of zero. So stepping-up via objects, the occasional "perfect" landing, colliding with an Egg Guard while simultaneously hitting the floor, and even full-jumping as Super Sonic in the THZ elevator can trigger this.

Also, completely related to Cobalt's post. Hitting a floor at zero vertical speed without stepping up will do it here for sure.
