It's not a workaround, it's the main way you are meant to use the browser :)

You'll find other servers' accounts and posts within your own server's web interface through the various discovery methods such as boosts, searches, tag following and the Explore tab.

If you want to browse another server's website directly, either use a browser extension or copy/paste the URL of a post or profile into the search box on your own server's website. Neither of these involves dialogue boxes.
