Unexpected autoplay behavior

I wanted to use `react-slick` in my project, since it's less than half the size of alternative libraries, but the autoplay feature seems to be pretty buggy.

The most noticeable and consistent issue is a small delay between transition animations, causing the loop to "jump".

Beyond that there are the issues others have mentioned, including random pausing on page interactions. I've also seen the carousel reverse directions for several slides, stopping, then continuing in the correct direction when switching tabs.

I have a [CodeSandbox demo here](https://codesandbox.io/s/react-slick-playground-forked-fnebl6), but these issues can also be seen on [your own demo](https://react-slick.neostack.com/docs/example/auto-play/) - particularly the reverse direction issue, which I have not seen in the CodeSandbox.
