Describe the Problem

Seems like FunctionFragment generates invalid full/minimal format from "full/minimal format string" with tuples
tuple(uint256)(uint256) - (uint256) is redundant here. Is it so?

Code Snippet

import { FunctionFragment } from 'ethers';

const fn1 = FunctionFragment.from('function swap(address,tuple(uint256))');
const fn2 = FunctionFragment.from(JSON.parse(fn1.format('json')));

console.log(fn1.format('full')); // function swap(address, tuple(uint256)(uint256))
console.log(fn2.format('full')); // function swap(address, tuple(uint256))

// FunctionFragment.from(fn1.format('full')); // Error
FunctionFragment.from(fn2.format('full')); // OK

Contract ABI

['function swap(address,tuple(uint256))']

Environment

Sorry. I missed tagging this in the fix included in v6.9.0. It was tagged with the issues #4329 and #4479.

Adding a note here with the tag GitPoap to remind me to flag this when building the GitPoap claim JSON.

Thanks! :)
