False positives on AddressDefaultWidgetTest::assertOptionSelected

  /**
   * Asserts that a select field has a selected option.
   *
   * @param string $id
   *   ID of select field to assert.
   * @param string $option
   *   Option to assert.
   * @param string $message
   *   (optional) A message to display with the assertion. Do not translate

PHPStan is saying this is a deprecated method, when it's not.

Call to deprecated method assertOptionSelected() of class [Drupal\Tests\address\FunctionalJavascript\AddressDefaultWidgetTest](https://api.drupal.org/api/drupal/core!tests!Drupal!Tests!address!FunctionalJavascript!AddressDefaultWidgetTest.php/class/AddressDefaultWidgetTest/9.4.0-beta1.x). Deprecated in drupal:8.2.0 and is removed from drupal:10.0.0. Use $this->assertSession()->optionExists() instead and check the "selected" attribute yourself.
