key = 'foo'
key.frozen? # => false TextFieldDefinition.create(key: key) key.frozen? # => true (not expected) I created a minimal example <https://gist.github.com/krisleech/017946a8c928c3f16ce1e54de09aab83#file-02_test-rb> to demonstrate the bug this but it does not reproduce it. It appears that in my production code `ActiveModel::Type::ImmutableString#cast_type`, which freezes the value, is called, but isn't in my attempt at a reproduction of the bug. Any ideas? I'm assuming Rails shouldn't modify input's in any way and should `#dup` them first.
