TextInput, don't count stripped characters?

                    TextInput::make('mobile')
->maxLength(11)
->minLength(11)
->mask(RawJs::make(<<<'JS'

//this code basically converts
xxxxxxxxxxx into xxxx xxx xx xx

let mask = function test(value) {
let val = value.replaceAll(' ', '');
switch (true) {
  case (val.length <= 4):
    return val;
  case (val.length <= 6):
    return val.substr(0, 4) + (val.length > 4 ? ' ' : '') + val.substr(4);
  case (val.length <= 8):
    return val.substr(0, 4) + (val.length > 4 ? ' ' : '') + val.substr(4, 3) + (val.length > 7 ? ' ' : '') + val.substr(7);
  default:
    return val.substr(0, 4) + (val.length > 4 ? ' ' : '') + val.substr(4, 3) + (val.length > 7 ? ' ' : '') + val.substr(7, 2) + (val.length > 9 ? ' ' : '') + val.substr(9);
}
}
$el.value =  mask($input);
