The core idea of that button is to lock the menu on so that you can more easily get to edit view on a given page. It's not widely used, and I'm not sure we really intended to lock _all_ the menus on.
Probably worth a bit more design. In the meantime, is it safe to assume that you can click the pin again to turn it off (as intended)?

Right! I had tried the un-clicking of the pin and didn't see results. But just realized it was probably a cookies issue, and low and behold, the un-clicking does work!
