Formatter "Link (with symbol)" [micon_link]: Title override not working

Okay I got the cause, but this needs a backend programmer.

Check this: https://git.drupalcode.org/project/micon/-/blob/2.x/modules/micon_link/src/Plugin/Field/FieldFormatter/MiconLinkFormatter.php?ref_type=heads#L170

Inside the foreach I printed:

  kint($title);
  kint($item);
  kint($item->title);

Result:

So from my point of view it needs to be something like this:

if ($title && !empty($item['#title'])) {
  $item['#title'] = $this->token->replace($item['#title'], [$entity_type => $entity]);
} elseif ($title) {
  $item['#title'] = $this->token->replace($title, [$entity_type => $entity]);
}

EDIT: My fix is incorrect because if the link title override field has no value, $item['#title'] is not empty; it falls back on the URL instead.

micon_linkit and micon_linkit_attributes are form field widgets, not display formatters? So, as far as I can see, this is the only formatter with this logic (in this module).

Okay all done and tested.
