Page is blank after clicking on RadioButton

To reproduce this bug:

Create blank Blazor server app

Replace site.css with:

html, body {
height: 100%;
margin: 0px;
padding: 0px;
line-height: 1.0;
overflow-y: hidden;

.comp-rows {
height: 100%;
overflow: hidden;
display: flex;
flex-direction: column;
flex-wrap: nowrap;

.comp-row-auto {
flex-grow: 0;

.comp-row-stretch-scroll {
flex: 1;
overflow: auto;

Replace Index.razor

@page "/"

<div class="comp-rows">

<div class="comp-row-auto">
<h1>Hello, world!</h1>
Welcome to your new app.

<div class="comp-row-stretch-scroll">

@for (int i = 1; i <= 100; i++)
string n = $"test{i}";

<EjsRadioButton Name="@n" Label="@n"></EjsRadioButton>



Now scroll Index page to the bottom, ckick on radio button and page goes blank.

Everything works if scrollpos = 0
