Blazor Server-side Loses Connection Upon Extended Phone Lock

This is based on this thread in the .NET Twitter Community/Group:

It appears that when a phone is locked for an extended period of time (10-20 minutes) and unlocked when visiting a Blazor server-side application, the connection is lost and it is not automatically reloaded, resulting in a poor user experience.

The connection appears to reconnect if locked for a few minutes, but for extended periods of time the connection gets lost altogether.

Describe the solution you'd like

When thinking of sites such as Twitter, Facebook, etc, which all use WebSockets, this issue does not occur to them and is accounted for with their own mechanisms. Ideally, this should also be easily addressed/configured with Blazor server-side applications as well. If the connection is lost, there should be the option to:

1. Ask the user to reload (current/default)
2. Automatically refresh the browser for the user without prompting
3. Attempt to re-establish/reconnect/recreate the connection without having the need to refresh the browser at all

Number 3 is the most ideal and should arguably be the default in future versions.
