• Extension version: v0.36.0
• VSCode Version: 1.64.1 (Universal)
• OS: macOS Monterey (12.2)

Steps to Reproduce:

1. Stage, commit and push a branch off master onto a GitHub Enterprise instance;
2. Issue the Pull Request command, and observe the fields in the Create Pull Request dialog in VS Code.

Expected behavior:

• "INTO" shows the repo in question and the "master" branch. (The repo is large, with hundreds of branches, or more. With a smaller repo, I do see this expected behavior.)

Actual behavior:

• "INTO" selects the very first branch available.
• Expanding the drop-down and scrolling ends at "j", so I can't choose "master."
• This means I can't properly create the PR for my commits.

Let me know if I can provide additional debugging information. Thank you!
