Maximum call stack size exceeded rendering three-level data structure in FlatList using @realm/react v0.4.3

Description

Hi, I am having trouble with my app crashing due to rendering too many Realm items in a FlatList. I have a three level deep nested data structure similar to what can be seen in this repo. I modified the project from this previous related issue. In this previous issue, the PR that fixed it made some changes to cachedObject.ts. I am running into an issue with this file in particular. In my internal company project, my app crashes after adding around 60-80 items depending on the device I test on. Here is a picture of the stacktrace. You can see the "Maximum call stack size exceeded while running cachedObjectHandler.get.

Unfortunately, I can't reproduce the issue in the repo I linked earlier, but the repo does show a similar three-level data structure (Task -> Subtasks -> SubSubtasks) to my project.
I am able to trigger the crash always by opening the app and adding 60-80 items. The interesting thing is that when I re-open the app, my previous 60-80 items I added before were there and it does not crash until I add another set of 60-80 items in that "session".
I downgraded my app to a version I had previously, before I upgraded my @realm/react from 0.4.1 to 0.4.3. The 0.4.1 version does not encounter this issue. I was able to add 100+ items and no crash. I reinstalled the 0.4.3 version and got the crash like stated earlier.
I'm not sure exactly how to get around this issue other than downgrading to 0.4.1, but I would like the fixes provided by 0.4.3.

Can you please help me take a look into this issue please?

@myou11 Thank you for reporting. It looks like you have found a regression in 0.4.3 but we need to investigate it further.

Your 60-80 items are on the root level, right? How many subtasks and subsubtasks do you have?

[myou11]

In my project, the equivalent to the reproduction repo would be: a Task is always added with at least one Subtask and at least one SubSubtask. For my testing, I only had one Subtask and SubSubtask under each Task, but 60-80 of those units as a whole would be enough to crash the app.

Thank you for taking the time to investigate!
