enum InstallResult { "success", "aborted", "invalid_data" };

// `installresult` is dispatched by the user agent at an <install> element to
// report the outcome of an install triggered by that element. The outcome is
// exposed on the event (`result`) rather than the element because it is a
// transient, per-activation signal, not persistent state.
//
// When the user agent dispatches this event it sets `bubbles = true` (see
// `HTMLInstallElement::DispatchInstallResultEvent`) so a page with several
// <install> elements can listen with one delegated handler on a common
// ancestor. Events constructed from script keep the standard `bubbles = false`
// default.
