Current behavior:
If you use the + and - zoom buttons in OpenSeadragon to adjust the zoom of an image, they are not constrained -- you can zoom in forever, beyond any configured limits. If you drag the image with the mouse, it will snap back to the configured zoom limit. It seems that something is bypassing the constraints (perhaps related to our reprogramming of the buttons during the accessibility sprint).

Expected behavior:
You should not be able to exceed zoom limits with the buttons; zooming should stop when a limit is reached, and further clicking should have no effect.

Steps to reproduce:

Keep clicking the - button: eventually, the image will reduce to a single pixel and disappear.

Keep clicking the + button: eventually, the image will zoom in so far that a single color fills the screen.
