I have a patch that wires up the "x" to close the popper, I didn't yet look into closing it if the user clicks onto something else.

So apparently OOUI sets tabindex="0" on the constraints icon, with that we can actually focus (and thus also handle blur). I'll do the same for us in order to re-implement the behavior as closely as possible.

@hoo cool. That sounds great and I remember us having to do the same thing with the modal type objects we built for termbox.

I just implemented it like this, but I'm not sure that's going to suffice… if the user clicks on the popper, this will probably also trigger the blur and thus close the popper. Maybe if the popper is a direct child of the TaintedIcon <a> this will work, but I'm not sure.
