09.08.2025: Experiment Annotation Popover in Detail View 🔍

Available in Phoenix 11.33+

We’ve added a new annotation popover feature on the experiment detail view: now when you click an annotation in the details panel, its full content is revealed in a popover. This makes it easier to view annotation details without navigating away.
