+/**
+ * #6701: a traceroute with many hops scrolled fine live, but was cut off with no way to scroll when reopened from
+ * history. Root cause: [MetricsViewModel.showTracerouteDetail] and [MetricsViewModel.showLogDetail] passed
+ * [MeshtasticDialog] a bare `SelectionContainer { Text(...) }` as `composableMessage` - [MeshtasticDialog] only adds
+ * `verticalScroll` to its own wrapping column when the dialog has `choices` (a button list), so a plain text dialog's
+ * scrolling is entirely the caller's responsibility.
+ *
+ * A screenshot can't catch this regression: a single frame of "scrolled to top, more content below" looks identical
+ * whether or not scrolling actually works. [performScrollTo] is the right tool instead - it throws when the target node
+ * has no scrollable ancestor, so it fails exactly when the `verticalScroll` wrapper is missing.
