Drop shadow transition flicker

I've added what I thought would be simple drop-shadow transition css but it's flickering. Check out the jsfiddle below to see what happens when you hover over the div.

How do I stop the flicker?

What am I looking for - I see a transition of the shadow from no shadow to the specified shadow and then a static shadow?

What should I be seeing?

Browser: FF

When viewing in Chrome, IE, or Opera it flickers through the transition. I can't test it on FireFox since running that executable is disabled through group policy.

Found a post (https://css-tricks.com/almanac/properties/b/backface-visibility/) that says this might help

-webkit-backface-visibility: hidden;

Open in new window

However, could not get it to work. Other research seems to indicate this is a known issue without a fix at present.

- FF is fine
- Chrome wobbles (could replicate)
- IE11 + IE10 seem fine - could not replicate
