Description

Undoing git changes throws ObjectDisposedException

Steps to recreate

1. Add a markdown file (in an asp.net non-core web application, if that matters)
2. With the editor open, undo git changes
3. Output from Markdown Editor shows an ObjectDisposedException was thrown.

Current behavior
