URL: https://github.com/apache/superset/pull/37018#issuecomment-3732916241
## **Sequence Diagram**
The PR changes tab refresh behavior so that when a tab becomes visible after
a dashboard-level refresh, the Tab component triggers a lazy chart refresh
(isLazyLoad=true) and guards duplicate handling to avoid updating global
refresh state — preventing infinite rerenders with nested tabs.
```mermaid
sequenceDiagram
participant Dashboard UI
participant Tab Component
participant Redux Dispatcher
participant Chart Refresher
Dashboard UI->>Tab Component: Tab becomes visible
(renderType=RENDER_TAB_CONTENT)
Tab Component->>Tab Component: check lastRefreshTime > tabActivationTime
&& not handled
Tab Component->>Redux Dispatcher: dispatch onRefresh(chartIds,
force=true, interval=0, dashboardId, isLazyLoad=true)
Redux Dispatcher->>Chart Refresher: refreshCharts(chartIds,...)
Chart Refresher-->>Redux Dispatcher: refresh complete
note right of Redux Dispatcher: because isLazyLoad=true, global
ON_REFRESH and filters refresh are NOT dispatched
```
