Describe the bug

When in the "Add New MCP Server" menu on Windows, Shift+Tab doesn't go back up the menu. It seems there is no way to get back to previous text boxes.

Affected version

0.0.335 Commit: 48dc015

Steps to reproduce the behavior

1. copilot
2. /mcp
3. a
4. enter some name
5. tab
6. try to shift+tab back up, nothing happens

Expected behavior

It clearly says "Tab/Shift+Tab: Navigate fields," which I expect to mean that Shift+Tab goes back up since Tab goes down.
