Which item teleports you randomly on taking damage?

Unless it was the Cursed Eye, which lets you do charged shots, I don't think it's an item at all. I just started a challenge run, and the only item I've picked up is the aforementioned Cursed Eye. But every time I take a single hit from the first boss, I'm immediately teleported out of the fight into another random room. It's making fighting the thing impossible.

So, it's either a side-effect of the Cursed Eye... Or it's a bug. My money's on the latter.
