I modified the customer address edit form in the Magento admin customer edit page, by adding some custom fields, and a switcherConfig to show hide fields conditionally. On page load it works fine. But if you close the modal and reopen it immediately, the switcherConfig no longer works.

There's a video recording show the problem in action here:

I have reported to Magento .

Has anyone else come across this odd behavior?

I created a small test module to reproduce on a vanialla installation. It's happening both on Magento 2.4.4 and 2.4.6.

Below is the test module's code.

app/code/Xtreme/TestSwitcherConfig/etc/module.xml

<?php

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Xtreme_TestSwitcherConfig',
    __DIR__
);
