Every message opened kept its full copy for as long as the tab was open. The store now holds bodies for the 40 messages most recently wanted; older ones go back to the list properties and are fetched in full again if opened. The open conversation is never released. Contact, settings and calendar exports go through downloadFile, which releases the object URL once the download has started; three of them never released it.
