Once ExportKeyStreamResource::handleRequest is entered, a 'Save As' dialog will be opened by the browser, even if key data is empty. This may happen if passphrase is wrong. If key data is generated before the download is actually requested, we can check if there is anything to push to browser and prevent the download request.
