Open "My Website" from Admin Menu Bar in a New Tab

Is your feature request related to a problem? Please describe.
Yes. It's a bit inconvenient when I click on "My Website" from the admin menu bar and it opens in the same tab, disrupting my workflow in the admin panel.

Describe the solution you'd like
I would like the "My Website" link on the admin menu bar to open the site in a new browser tab instead of the same tab.

Describe alternatives you've considered
As a workaround, I currently right-click the link and select "Open in new tab," but this slows down the process and isn't very intuitive for all users.

Additional context
This small change can improve usability for admins who need to toggle between the backend and frontend frequently without losing their current admin panel view.

Locate the React admin menu bar component that renders the “My Website” link and inspect how its navigation target is set. Update the link behavior so it opens the frontend in a new browser tab, then verify that the admin panel remains open while the site loads separately.
