According to all the answers on how to hide scrollbars while allowing scrolling, the standard approach is
.hidescrollbar {
    -ms-overflow-style: none;  /* Internet Explorer 10+ */
    scrollbar-width: none;  /* Firefox */
}
.hidescrollbar::-webkit-scrollbar { 
    display: none;  /* Safari and Chrome */
}
But I tried this in Firefox 71 and the style scrollbar-width: none; (which is meant for Firefox) doesn't work. In FF 71 I see the scrollbars show up when the viewport is exceeded.
Something has changed (since FF66+?) and this poster has also raised this issue. His solution is to make the FF scrollbar transparent. But it still takes up space, whereas I need to hide it completely.
Are there any solutions for the latest versions of FF to replace scrollbar-width: none;?
