/**
 * The embedder script is a cross-origin script from js.hubspot.com, and nothing
 * makes the widgets wait for it: they read its globals off `window` the moment a
 * control renders. On sites where an asset pipeline defers it, or where the
 * editor is simply slow, the widget can lose that race and fail permanently even
 * though the script arrives seconds later.
 *
 * Resolves true as soon as the globals appear, or false once the wait is up.

 * configured with a shouldSendCallback that drops any event whose culprit does
 * not match plugins/leadin/, and captureMessage does not attach a stack trace,
 * so it has no culprit to match on.
