FormRegistrarMixin is registering array name with []

[geniuspacs]

Recently we are building a fieldset which have an array as modelValue, something like this:

{
  citizenships: [
    { code: 'ES', description: 'España' },
    { code: 'PT', description: 'Portugal' }
  ]
}

And we are trying to build this structure at our HTML template:

<ing-fieldset name="citizenships[]">
  <ing-input name="code"></ing-input>
</ing-fieldset>
<ing-fieldset name="citizenships[]">
  <ing-input name="code"></ing-input>
</ing-fieldset>

But result on modelValue is something like this, which means is registering including '[]':

And for sure, fields inside each fieldset are empty. Is that correct? Should we register including '[]' in modelValue also? I think we should avoid to include this characters and use only in terms of registering FormControl as array, but I would love to know what do you think guys.

Cheers!
