Blazor Server registers page 'unload' event instead of the recommended 'pagehide' or 'visibilitychange events about aspnetcore

I stand corrected. Now it happens in Edge. I feel like something I just did might have caused this, because it worked earlier today.
Investigating.

Could you post a repro app (as a public GitHub repo) and full steps to reproduce the problem?

add some components or buttons on the page, this happens

This is a bit too vague 😄 What specifically should be added, and what gestures do you do in the browser in order to get to this warning?

I refactored my project from the Blazor Web App Template, and I no longer have the problem. I still see the warning in Browser Dev Tools that Unload was removed, but it doesn't throw any errors.

If it happens again I will open a new issue.
