Layout/FirstMethodArgumentLineBreak errors out passing hash in super with brackets

[AirWick219]

Layout/FirstMethodArgumentLineBreak cop errors out while inspecting this line.

def initialize(fruits:)
  super( fruits: fruits ) <--- "An error occurred while Layout/FirstMethodArgumentLineBreak cop was inspecting "
end

But it works if I do this

def initialize(fruits:)
  super({ fruits: fruits })
end

---

Expected behavior

No error

Actual behavior

1 error occurred:
An error occurred while Layout/FirstMethodArgumentLineBreak cop was inspecting

Steps to reproduce the problem

Add the above line in a method that with the hash key without the bracket.

This issue is a dup with #8444 and resolved by #8445. Thank you.

@koic Thanks a lot for the heads up. I am curious about what happened. The only thing changed in the bundle was rubocop-ast updated from 0.1.0 -> 0.3.0 and looking the CHANGELOG.md it doesn't seem like anything might have caused it.

I double checked rubocop-ast 0.2.0 and it works. Seems like this issue was introduced in rubocop-ast 0.3.0

That's my fault, sorry about that. This is due to an optimization I did, but didn't think about possible consequences which is that result of arguments is now sometimes frozen. My personal style is of using more and more immutable data and I try to never mutate results from getters, so I didn't think about it...

I'm adding a reference to this in the Changelog now. Maybe arguments should always return a frozen object too...?
