- [26636](https://github.com/apache/superset/issues/26636): Sets the `DASHBOARD_VIRTUALIZATION` feature flag to `True` by default. This feature was introduced by [21438](https://github.com/apache/superset/pull/21438) and will enable virtualization when rendering a dashboard's charts in an attempt to reduce the number of elements (DOM nodes) rendered at once. This is especially useful for large dashboards.
