Actually, it's correct. A lazy() that resolves to an array in the child of a component should be equivalent to that being an array in the first place which wouldn't have the nested slots. So both cases should be equivalent. |
It's possible to postpone a specific node and not using a wrapper component. Therefore we encode the resumable slot as the index slot. When it's a plain client component that postpones, it's encoded as the child slot inside that component which is the one that's postponed rather than the component itself. Since it's possible for a child slot to suspend (e.g. React.lazy's microtask in this case) retryTask might need to keep its index around when it resolves.

Since we know that we're not going to suspend again (we asssume the iterator doesn't) and we know we're about to call renderChildrenArray again. We can just do that directly instead of going through renderNode another time. This also helps separate these two paths a bit so it can have different logic.

This is still not quite right. If you have a React.lazy or Usable inside a nested array it should still have the extra key path with extra slot before it. The isArray check isn't enough to determine if it's nested. This means this information must also survive spawning a task. This also is relevant to the resuming path because it's different whether the resuming happens at a point that can return a root array or resumes in the slot inside the root array. |
