Firefox Has Problems With smoothHeight

With smoothHeight on and in Firefox 22.0, when I resize the browser window quickly and let go of the mouse button before the animation finishes, the Flexslider has an incorrect size. For resizing smaller, there is a noticeable gap beneath the slider. For resizing bigger, the slider height is cut short.

• As soon as I start resizing again, the size adjusts to what it should be in both cases.
• When the slide automatically changes, the size also adjusts to what it should be.

Normal size:

Resize smaller, creates a gap underneath slider:

Resize bigger, slider height is cut short:

After some Googling, I read that Firefox apparently has some issues with Flexslider. I tested this problem on Chromium and it does not occur there.

I listed this as a Flex Slider Library problem because the problem exists on the Flex Slider Smooth Height Demo page as well:

Anybody have any suggestions or ideas?
