The following code sample does not smoothly scroll in Chrome 67; when you use a mouse to grab the scrollbar, you will notice the scrollbar drag gets aborted every 1 second when the timer updates the text in the title.
<html><body style="margin:0pt;">
<div style="height:100vh;overflow:hidden;display:grid;grid-template-areas:'topbar' 'body'">
<div style="grid-area:topbar;background-color:lightblue">
This is a fixed top bar with ticker: <span id="ticker">0</span>
</div>
<div style="grid-area:body;font-size:200pt;overflow:auto;">
Try and scroll down! a a a a a a a a a a a a a a a a a
</div>
</div>
<script type="text/javascript">
setInterval(function(){
document.getElementById("ticker").innerHTML = Number(document.getElementById("ticker").innerHTML) + 1;
}, 1000);
</script>
</body></html>
It works as expected in Edge.
Is there a solution to this problem?
