This function is used to detect file downloads. If there is a file download then we get a beforeunload event, but the page is never unloaded and when the file download completes we should re-enable the buttons. We detect this by watching for a specific cookie.
PHP function \core_form\util::form_download_complete() can be used to send this cookie.
