Thanks for the feedback. Are you still having this issue? I am unable to reproduce the issue but will keep an eye out for posts that exhibit similar behavior. Have you tried clearing your browser cache?
I'm seeing the same problem. Open this link and then resize the browser. It's very apparent.
The behavior is identical in Google Chrome, Mozilla Firefox, Microsoft Edge, and Microsoft Internet Explorer 11.
I have escalated this issue and it is currently under review. I will provide additional updates as soon as they are available.
If my browser window is "wide" when I load the page I can usually get it to display correctly.
If I start out with a "narrow" browser window, it doesn't seem fixable.
All of my experimentation is with IE 11.
