removeFeatureState does not remove state from the original zoom level

[asheemmamoowala]

Steps to reproduce

https://jsfiddle.net/u3cvf8sx/

1. Click on Africa to highlight (notice we are default to zoom level 1).
2. Now zoom in via mouse scroll wheel until zoom level changes to 2 or higher.
3. Now click anywhere in ocean area, and the highlight on Africa will disappear as expected. This is achieved by calling removeFeatureState on the layer.
4. Now without clicking anything but use mouse scroll wheel to zoom out again back to zoom level 1.

Expected behavior

highlight is removed for all zoom levels

Actual behavior

The highlight is back again for zoom level 1 only. As if the feature's state at zoom level 1 hasn't been removed.
