Hi, I have a website that has a sticky button at the end of the page - as you can imagine I am using `position: fixed` and `bottom: 0` to set it there - Testing my site on Mozilla for android I discovered that when I click this button the text within it disappears but it only happens if there is more content and you scroll the page until the end, then If I scroll the content up a bit the text appears. I recorded a video where you can see the issue: https://youtu.be/2rz-AjRtp9M here the code sandbox with the code you see in the video: https://codesandbox.io/s/quirky-carson-5ksot
