Rectangle selection also kind of bugs out when you reach the edge of the axes. I looked into fixing this a while ago and had a partial solution. The rectangle selector does some inaxes checking and relies on the xdata and ydata values. These are invalid outside the axes, but you can fake it by using the pixel values and a the axes transform. It might be worth adding a parameter to the rectangle selector to allow or disallow the rectangle to go outside of the axes. -Ben

I'd just like to point out that it's the UI that's deceptive: you can actually zoom to the edges by doing just what you'd expect, but the box showing where you're zooming to is wrong.
