    //
    // This first principle is that if we're going to suspend when we complete
    // a root, then we should also restart if we get an update or ping that
    // might unsuspend it, and vice versa. The only reason to suspend is
    // because you think you might want to restart before committing. However,
    // it doesn't make sense to restart only while in the period we're suspended.
    //
    // Restarting too aggressively is also not good because it starves out any
    // intermediate loading state. So we use heuristics to determine when.
    // Suspense Heuristics
    //
    // If nothing threw a Promise or all the same fallbacks are already showing,
    // then don't suspend/restart.
    //
    // If this is an initial render of a new tree of Suspense boundaries and
    // those trigger a fallback, then don't suspend/restart. We want to ensure
    // that we can show the initial loading state as quickly as possible.
    //
    // If we hit a "Delayed" case, such as when we'd switch from content back into
    // a fallback, then we should always suspend/restart. Transitions apply
    // to this case. If none is defined, JND is used instead.
    //
    // If we're already showing a fallback and it gets "retried", allowing us to show
    // another level, but there's still an inner boundary that would show a fallback,
    // then we suspend/restart for 500ms since the last time we showed a fallback
    // anywhere in the tree. This effectively throttles progressive loading into a
    // consistent train of commits. This also gives us an opportunity to restart to
    // get to the completed state slightly earlier.
    //
    // If there's ambiguity due to batching it's resolved in preference of:
    // 1) "delayed", 2) "initial render", 3) "retry".

    // different layout, where the child points to a dehydrated fragment, which

    // 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
