// allow any data to leak due to cached values.

// Step 1: Load browser_privatebrowsing_localStorage_before_after_page.html in a private tab, causing a storage
//   item to exist. Close the tab.
// Step 2: Load the same page in a non-private tab, ensuring that the storage instance reports only one item
//   existing.
