Description

## Is this a Bug or Feature request?:
Bug

## Steps to reproduce:
1. Create a new blazor project `dotnet new blazor`
2. Make a code change and verify the message "Code changes were successfully applied."
3. Switch back to the browser.
4. Observe that the browser is not automatically refreshed to reflect the changes.
5. Manually reload the page to see the applied changes.
## Description of the problem:
I tired the new experimental hot reload feature in C# Dev Kit. After making a code change and seeing the message "Code changes were successfully applied," the browser does not automatically refresh. The changes are only visible after manually reloading the page.

## Expected behavior:
The browser should automatically refresh to display the latest changes made in the code.

## Actual behavior:
The browser does not refresh automatically after code changes. The updated content is only visible after manually reloading the page.
