Blame width not adjustable.

[BanksySan]

Describe the bug
When I view the blame annotations the width of the blame window is about 50% of the code window which makes it very difficult to work with.

To Reproduce
Steps to reproduce the behavior:

1. Create a Git repo and some commits.
2. Open file with a history.
3. Right-click and show blame annotations
4. Try to change size of window.

Expected behavior
Reduce size of window so that I can clearly see the code.
