There was a problem hiding this comment.
I'm wondering if this will reintroduce the other bug that was fixed when you introduced key support. We got into a weird state where the root chunk never resolved to a value and always fullfilled with null. Maybe the other change where the model root condition is checked first is what resolved that though

Yes. Either the lazy or the modelRoot thing should fix that issue so we have at least the other fix. |

…suspend (#28283) In #28123 I switched these to be lazy references. However that creates a lazy wrapper even if they're synchronously available. We try to as much as possible preserve the original data structure in these cases. E.g. here in the dev outlining I only use a lazy wrapper if it didn't complete synchronously: https://github.com/facebook/react/pull/28272/files#diff-d4c9c509922b3671d3ecce4e051df66dd5c3d38ff913c7a7fe94abc3ba2ed72eR638 Unfortunately we don't have a data structure that tracks the status of each emitted row. We could store the task in the map but then they couldn't be GC:ed as they complete. We could maybe store the status of each element but seems so heavy. For now I just went back to direct reference which might be an issue since it can suspend something higher up when deduped. DiffTrain build for [ba5e6a8](ba5e6a8)
