     * Summary of `ReactBrowserEventEmitter` event handling:
     *
     *  - Top-level delegation is used to trap most native browser events. This
     *    may only occur in the main thread and is the responsibility of
     *    ReactDOMEventListener, which is injected and can therefore support
     *    pluggable event sources. This is the only work that occurs in the main
     *    thread.
     *
     *  - We normalize and de-duplicate events to account for browser quirks. This
     *    may be done in the worker thread.
     *
     *  - Forward these native events (with the associated top-level type used to
     *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
     *    to extract any synthetic events.
     *
     *  - The `EventPluginHub` will then process each event by annotating them with
     *    "dispatches", a sequence of listeners and IDs that care about that event.
     *
     *  - The `EventPluginHub` then dispatches the events.

     *
     * Only change is we use console.warn instead of console.error,
     * and do nothing when 'console' is not supported.
     * This really simplifies the code.
     * ---
     * Similar to invariant but only logs a warning if the condition is not met.
     * This can be used to log issues in development environments in critical
     * paths. Removing the logging code for production environments will keep the
     * same logic and follow the same code paths.

    //
    // Like fibers, update queues come in pairs: a current queue, which represents
    // the visible state of the screen, and a work-in-progress queue, which can be
    // mutated and processed asynchronously before it is committed — a form of
    // double buffering. If a work-in-progress render is discarded before finishing,
    // we create a new work-in-progress by cloning the current queue.
    //
    // Both queues share a persistent, singly-linked list structure. To schedule an
    // update, we append it to the end of both queues. Each queue maintains a
    // pointer to first update in the persistent list that hasn't been processed.
    // The work-in-progress pointer always has a position equal to or greater than
    // the current queue, since we always work on that one. The current queue's
    // pointer is only updated during the commit phase, when we swap in the
    // work-in-progress.
    //
    // For example:
    //
    //   Current pointer:           A - B - C - D - E - F
    //   Work-in-progress pointer:              D - E - F
    //                                          ^
    //                                          The work-in-progress queue has
    //                                          processed more updates than current.
    //
    // The reason we append to both queues is because otherwise we might drop
    // updates without ever processing them. For example, if we only add updates to
    // the work-in-progress queue, some updates could be lost whenever a work-in
    // -progress render restarts by cloning from current. Similarly, if we only add
    // updates to the current queue, the updates will be lost whenever an already
    // in-progress queue commits and swaps with the current queue. However, by
    // adding to both queues, we guarantee that the update will be part of the next
    // work-in-progress. (And because the work-in-progress queue becomes the
    // current queue once it commits, there's no danger of applying the same
    // update twice.)
    //
    // Prioritization
    // --------------
    //
    // Updates are not sorted by priority, but by insertion; new updates are always
    // appended to the end of the list.
    //
    // The priority is still important, though. When processing the update queue
    // during the render phase, only the updates with sufficient priority are
    // included in the result. If we skip an update because it has insufficient
    // priority, it remains in the queue to be processed later, during a lower
    // priority render. Crucially, all updates subsequent to a skipped update also
    // remain in the queue *regardless of their priority*. That means high priority
    // updates are sometimes processed twice, at two separate priorities. We also
    // keep track of a base state, that represents the state before the first
    // update in the queue is applied.
    //
    // For example:
    //
    //   Given a base state of '', and the following queue of updates
    //
    //     A1 - B2 - C1 - D2
    //
    //   where the number indicates the priority, and the update is applied to the
    //   previous state by appending a letter, React will process these updates as
    //   two separate renders, one per distinct priority level:
    //
    //   First render, at priority 1:
    //     Base state: ''
    //     Updates: [A1, C1]
    //     Result state: 'AC'
    //
    //   Second render, at priority 2:
    //     Base state: 'A'            <-  The base state does not include C1,
    //                                    because B2 was skipped.
    //     Updates: [B2, C1, D2]      <-  C1 was rebased on top of B2
    //     Result state: 'ABCD'
    //
    // Because we process updates in insertion order, and rebase high priority
    // updates when preceding updates are skipped, the final result is deterministic
    // regardless of priority. Intermediate state may vary according to system
    // resources, but the final state is always the same.
