Incorrect field name parsing

[inoyakaigor]

I found that class properties that is arrays has incorrect names in logs but not all the time:

I think in case of correct name changed exactly this property (store.arrayField): [] → [{…}, {…}, {…}]
While name is incorrect the changes are taking place within the object: store.arrayField[0].someProp = 1

UPD:
It happens there:

result:

Thanks, probably it's better to keep the original name here
