I am trying to create a filter that shows all issues that have a blocker comment. When I search for `"Blocker Comment[Paragraph]" is not empty` I get issues that have a blocker comment (good), but I also get issues that used to have a blocker comment (bad). So if I add a blocker comment to an issue, then clear the blocker comment out, the filter will still surface that issue.
How do I create a filter that only returns issues that currently have a blocker comment?
