Thanks for responding.

If I understand what you are suggesting then the problem is that the
vertical scroll of the page would be reset. There is no guarantee that the
page load will happen quickly. The user will most likely see the navigation
occur and then the original page refresh. I want to cancel navigation
before it ever occurs.

The browser widget I’m working with is a Froala editor. The user will be
inserting their own content into the browser widget.
