/**
 * withDomainRequired is a higher-order component (HOC) meant to be used with <Route /> components within
 * static/app/routes.tsx whose route paths do not contain the :orgId parameter.
 * For example:
 *
 *  <Route
 *    path="/issues/(searches/:searchId/)"
 *    component={withDomainRequired(errorHandler(IssueListContainer))}
 *  / >
 *
 * withDomainRequired ensures that the route path is only accessed whenever a customer domain is used.
 * For example: orgslug.sentry.io
 *
 * The side-effect that this HOC provides is that it'll redirect the browser to sentryUrl
 * (from window.__initialData.links) whenever one of the following conditions are not satisfied:
 *
 * - window.__initialData.customerDomain is present.
 * - window.__initialData.features contains organizations:customer-domains feature.
 *
 * If both conditions above are satisfied, then WrappedComponent will be rendered with orgId included in the route
 * params prop.
 *
 * Whenever https://orgslug.sentry.io/ is accessed in the browser, then both conditions above will be satisfied.
