Dashboard lockup

[Michael Aston]

I have a problem with the dashboard sometimes locking up when the browser is resized. Its a difficult issue to reproduce but I finally have a test case which I've attached with a video in the root. From the video you can see the CPU usage by Chrome pickup once the lock up occurs. I think the issue is which a piece of javascript I have that changes the number of columns on the dashboard as the browser changes to give it a responsive feel. If I disable this code the locked does not occur.

protected async Task DashBoardCreate()

        {

            await JSRuntime.InvokeAsync<string>("DashBoardResizeHandler", new object[] { DotNetObjectReference.Create<object>(this) });

        }

Sorry forgot to add that the browser size is important. I reproduced the lockup in chrome with the html body size of 696x1249.330.
