toggle button is not visible on first load of the page.

So on the latest version of this lib, it seem's that the toggle switch isnt showing all the time, as you can see in the three images, the first image is how the page is visible in chrome when the page loads. As you notice you can't see the white toggle button at all, as soon as you click "Yes" it becomes visible.

On Load

On Toggle Off

On Toggle On

I am unable to reproduce this myself.
Do you some example code you can share?
It would be worth checking if something else from your stylesheet is overriding the border css styling, as that looks like what could be happening here.
