A part of return value of "paramType.format("json")" is missing.

When the value of type that is a property of paramType, is tuple[], components that part of the return value of the method paramType.format("json") is missing.

I think this process is done in the following source:
https://github.com/ethers-io/ethers.js/blob/c785c1e5153d5a85a78f90f177577f2c8df15529/src.ts/abi/fragments.ts#LL606C12-L606C12
It seems to me that the process that generates components' from 'arrayChildren' is missing when baseType === "array".

Reproduced at
https://codesandbox.io/s/paramtypejsonformattest-tx8zub?file=/src/index.js

Is this a bug? If not, is there any way to restore the original JSON from paramType?
