openseadragon: constrainDuringPan causes jitter on mobile

While the constrainDuringPan option stops you being able to pan the image too far away from the edges before it springs back, I would like to able to stop this behaviour completely - is this possible?

For example at the moment you can pan further left than the edge of the image, a bit of background is shown and then it springs back. I’d like the user to only be able to pan to the edge of the image and no further.

Is this possible or is there an option for this? I can’t see it myself.
