openseadragon zoom direction

I am developing using Openseadragon When I am zooming in using mouse wheel and reading the value of the current zoom using the function getZoom() , I am getting the value of the zoom for each wheel step

When I keep scrolling the mouse wheel in the up direction the zoom value keep changing normally as expected , going bigger. But on a direction change of the mouse wheel , going down , ( in the first step only ) the zoom value continue to rise ( getting bigger ) but it should decrease ( getting smaller )

I think it is a bug of the Openseadragon , does anyone can help on the issue ? any info ?

I would think what you're seeing is because of the spring animation (slowing the zoom change exponentially as the zoom approaches the target level) after each wheel event.

If you use getZoom(false) you'll get the target zoom, which should change sign when you change the wheel direction.
