    // 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,

    //
    // If this is an initial render of a new tree of Suspense boundaries and
    // those trigger a fallback, then don&#039;t suspend/restart. We want to ensure
    // that we can show the initial loading state as quickly as possible.
    //
    // If we hit a &quot;Delayed&quot; case, such as when we&#039;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&#039;re already showing a fallback and it gets &quot;retried&quot;, allowing us to show
    // another level, but there&#039;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&#039;s ambiguity due to batching it&#039;s resolved in preference of:

    // First, Legacy Mode has different semantics for backwards compatibility. The
    // primary tree will commit in an inconsistent state, so when we do the

    // hacks to make that not totally break. Like transferring effects and
    // deletions from hidden tree. In Concurrent Mode, it&#039;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&#039;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&#039;re currently rendering. Ideally we would model this using
