Unlinking a Maven project doesn't remove the project/repository from the Branches pane in Git tool window

Problem

When a Maven project is linked via the right-side Maven tool window in the IDE, and later unlinked, it still appears in the Branches pane in the Git tool window, creating potential confusion for users.

Cause

The Branches widget displays git roots that are detected in the project tree. It doesn't relate to Maven projects.

Resolution

To address this issue, follow these steps:

To manage git roots displayed in the Branches pane, go to - Settings (⌘ + , or Ctrl + Alt + S) > Version Control > Directory Mappings > select the relevant root and click the minus (-) button to remove it.
