It seems that removing local storage item by Storage.removeItem()(https://developer.mozilla.org/en-US/docs/Web/API/Storage/removeItem) removes item from the database but it does not remove the item from the cache of SQLiteStorageArea. It can lead to increase memory usage on Network process. I found this issue when I was working on fix for https://bugs.webkit.org/show_bug.cgi?id=250470
