CSS alignment issues from Firefox version 57 onward

Question

I have a webpage and one of the element in it had the following style:

{
  width: 100%;
  min-width : 100%;
  height : 30px;
}

This was working perfectly with all the zoom options in Firefox versions prior to 57. But with Firefox version 57 and above, the alignment is completely distorted and is changing with zoom options. Can you please assist on this?
