Metric detail view: show the current equation's calculation, and fix chart panel that cannot be scrolled

Problem Statement

On a saved metric's detail view, the chart renders against the equation as it was historically defined. Users expect to also see what the metric evaluates to under its current equation, but that current calculation is not clearly surfaced. Compounding this, the area where users expect to scroll to reach that information cannot be scrolled at all.

Why the current behavior is insufficient
After editing a metric, users have no clear way to confirm the metric is now computing what they intend. The missing "current" view plus an unscrollable panel means expected content is effectively hidden, leaving users unsure whether their change took effect.

Solution Brainstorm

Clearly distinguish and label a "historical (as-defined)" series vs. the "current equation" calculation, or provide a toggle between them. Separately, fix the detail/chart panel so it scrolls and all content is reachable (this part is likely a UI bug).

Product Area

Alerts

Start at the saved metric detail view and reproduce the behavior after editing a metric: inspect the chart panel where scrolling fails and identify how the displayed equation is selected. Done means users can reach all detail content and can clearly distinguish the historical series from the calculation under the current equation.
