Permissions unassigned when using multiple windows/tabs on same session

With multilingual site. Validate the form with $submit_button['#value']->render() == 'Save permissions' is not working because in another language, we will have another value for button. So I think it's better if give the submit button a value that we can detect when click this button, and validate the form with this value, somthing like that:
alter form:
$form["actions"]["submit"]['#saved_permission'] = TRUE;
and validate function will be:

$submit_button = $form_state->getTriggeringElement();
  // no need to run this validation when submitting filter changes.
  if (isset($submit_button['#saved_permission'])) {
