         * scheduled asynchroneously, avoiding recursive calls in the same tick.
         *
         * The task itself is implemented in `doTick`. It can be requested and called for single execution
         * using the `tick` method.
         *
         * It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
         * no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
         *
         * If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
         * and cancelled with `clearNextTick`.
         *
         * The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
         *
         * Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
         *
         * Further explanations:
         *
         * The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
         * only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
         *
         * When the task execution (`tick` method) is called in re-entrant way this is detected and
         * we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
         * task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

 * is invoked more than once during the `wait` timeout.

 * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
 * until to the next tick, similar to `setTimeout` with a timeout of `0`.

      // state, no effects. Same as what we do for Offscreen (except that
      // Offscreen doesn't have the first render pass).
      //
      // Second is hydration. During hydration, the Suspense fiber has a slightly
      // different layout, where the child points to a dehydrated fragment, which
      // contains the DOM rendered by the server.
      //
      // Third, even if you set all that aside, Suspense is like error boundaries in
      // that we first we try to render one tree, and if that fails, we render again
      // and switch to a different tree. Like a try/catch block. So we have to track

            // 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
