• Extension version: v0.48.1
• VSCode Version: 1.70.2
• OS: macOS Monterey 12.5

Steps to Reproduce:

1. Click the + button to add an assignee, ensure there is yourself and a suggested user
2. Add a suggested user and click ok, note that this adds yourself as a reviewer instead

Other notes:

• It is possible to add yourself multiple times with this method. This does not propagate to github, only the one instance is shown
• Adding non suggested users works as expected
• Selecting yourself from suggested also adds yourself
