  // - First execution of component function: user functions are double invoked
  // - Second execution of component function (in Strict Mode, during
  //   development): user functions are not double invoked.

  //
  // 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".
  //
  // We want to ensure that a "busy" state doesn't get force committed. We want to
  // ensure that new initial loading states can commit as soon as possible.

  // First, Legacy Mode has different semantics for backwards compatibility. The
  // primary tree will commit in an inconsistent state, so when we do the
  // second pass to render the fallback, we do some exceedingly, uh, clever
  // hacks to make that not totally break. Like transferring effects and
  // deletions from hidden tree. In Concurrent Mode, it's much simpler,
  // because we bailout on the primary tree completely and leave it in its old
  // 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
  // which branch we're currently rendering. Ideally we would model this using
  // a stack.
