Wheel numbers visible outside wheel

Question

With v:2.4, FF18, using datetime demo, if I click-drag the number wheel up/down, the numbers go momentarily outside the wheel area, then disappear and then wheel is actually scrolled. This did not happen in v:2.0. Is there a way to avoid this effect, or is it a bug?

Sorry, hard to get a screen shot; it just happens for an instant, but looks ugly.

Looks like it's fixed in 2.4.1 The issue did not happen in 2.0 (and 2.1) because the top property was animated instead of the hardware accelerated translate3d, which provides more fluid animations, but appears to behave funky on FF18.

Surprisingly removing the border-radius from the .dww class (the animation container) looks like solved the issue.
