// invokeGuardedCallback uses a try-catch, all user exceptions are treated
// like caught exceptions, and the DevTools won't pause unless the developer
// takes the extra step of enabling pause on caught exceptions. This is
// unintuitive, though, because even though React has caught the error, from
// the developer's perspective, the error is uncaught.
//
// To preserve the expected "Pause on exceptions" behavior, we don't use a
// try-catch in DEV. Instead, we synchronously dispatch a fake event to a fake
// DOM node, and call the user-provided callback from inside an event handler
// for that fake event. If the callback throws, the error is "captured" using
// a global event handler. But because the error happens in a different
// event loop context, it does not interrupt the normal program flow.
// Effectively, this gives us try-catch behavior without actually using
// try-catch. Neat!

// DEV version of invokeGuardedCallback
