<Fill/> width can exceed <ViewPort/> width about react-spaces

@Slapbox. I seemed to have tracked down the cause of this issue to a race condition in the resize operation. Looking at the code there was a possibility that the handler which deals with mouse/touch moves during a resize operation could also fire after the resize operation had completed and also after the onResizeEnd callback. This would result in the out of sync UI that you have seen.

I've put a fix in v0.4.1 which now hopefully fixes this issue.

Thanks for your awesome work @aeagle!

I can't recall the last time I saw this issue so maybe whatever I was experiencing - I think we found a workaround for our use-case because we're on 0.3.6 currently and I haven't seen the issue in ages. As such, unfortunately I can't confirm the fix on my end - but I think this issue can be considered resolved!

Apologies for forgetting to update the issue, and a big thanks to you for not forgetting about it!
