No file or test is named in the issue. Reproduce the My Site flow by enabling airplane mode, showing the offline banner, and triggering pull-to-refresh; then compare the stale dashboard feed and snackbar behavior with the documented expected behavior. Done means the stale feed message and dashboard snackbar appear instead of the generic no-network toast.
