Thanks for the detailed bug report!

When formatting repeatedly

If you wait a bit for formatting to complete, and then continue to repeat the action, does the issue still occur? I suspect we might be missing a check somewhere to prevent concurrent batch operations.

I am unable to reproduce this issue. Closing for now due to lack of information needed to help debug, but please reactivate if you are still encountering this on the latest versions of VS and XAML Styler.
