The built-in browser doesn't URL-encode spaces. Instead, it treats the input as a search query.

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.129.1
• OS Version: Windows 11

Steps to Reproduce:

Try entering a URL that contains a space, for example: http://localhost:8888/my file.php (there is a space between my and file.php).

Expected Behavior:

In other browsers, such as Brave (Chromium), entering the same URL automatically results in a request being sent to:

http://localhost:8888/my%20file.php

In other words, the browser automatically URL-encodes the space as %20 before sending the request.
