Issue Summary

• Editing a comment after 30 minutes with attachment errors out with the error - "We couldn't save your comment. It might be empty or have invalid formatting. If you copy-pasted, try removing the formatting and adding it directly in the editor."
• 

Steps to Reproduce

1. Add a text comment on any work item.

1. Once 30 mins pass, edit the comment with a direct attachment (either pasting a screenshot directly or via the attach button), and this would fail. 

1. NOTE: Do not reload the page in the meantime.

Expected Results

The attachment addition in the comment should succeed, but it fails.

Actual Results

Save fails, and we get the error - "We couldn't save your comment. It might be empty or have invalid formatting. If you copy-pasted, try removing the formatting and adding it directly in the editor."

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
