Describe the Bug
When Clicking on a commit, it shows commit detail and when I hover on a file it will show some action buttons, such as:

• Copy File Path to the Clipboard
• View File at this Revision
• Open File

But when Git Graph opened in small window or tab, some buttons got truncated, makes it unclickable.

Steps to Reproduce
Steps to reproduce the behaviour:

1. Open Git Graph on small tab or vs code window.
2. Click on some commit
3. Hover over on some file which changed in that commit
4. See Some button got truncated and unclickable

Expected Behaviour
Button don't get truncated so I can click it.

Environment

• Git Graph Extension Version: 1.26.0
• Visual Studio Code Version: 1.49.0
• Operating System: Manjaro Linux 20.1

Screenshots (optional)
