XF 2.3 verifyOption not being called

[Spectral-Brain]

I have extended AbstractOption to create a custom Option. renderOption is being triggered but when I click Save in the Admin Options, it doesn't seem to trigger the verifyOption as I have logging in there that isn't being triggered.

I've tried

public static function verifyOption(&$value, \XF\Entity\Option $option)

as well as

public static function verifyOption(&$value)

and neither seem to be triggered.

I have also tried specifying a validation class as well as not specifying it in my option.

<?xml version="1.0" encoding="utf-8"?>
<options>
  <option option_id="contactFormRules" edit_format="callback" data_type="array" validation_class="SpecModz\ContactFormOverride\Option\ContactFormRules" validation_method="verifyOption" advanced="0">
    <default_value>[]</default_value>
    <edit_format_params>SpecModz\ContactFormOverride\Option\ContactFormRules::renderOption</edit_format_params>
    <sub_options>*</sub_options>
    <relation group_id="contactFormOverride" display_order="1"/>
  </option>
</options>

Any thoughts on why this isn't being triggered?
