radix popover - form submission

Cant help you if I dont know what the problem is. Please share

1. what the exact problem is
2. a builder link

this is a link to an example. expected behaviour would be to click the button open the popover contents (which in this case is a login form) and be able to submit the form.
seems to get caught on toLowerCase (at least in the console)

if you pull the form outside of the radix popover you can then submit the form

I created a minimal version of this to narrow down the issue. Minimal version does not have the issue so I suspect custom code at play is messing it up. Try removing things to see what's causing the issue. Btw when i tried the login form, nothing happened, including no error in the console.

Here's my minmal attemtp at reproduction

how do i create that button that closes either the radix popover or the dialog box. i can't see anything on the existing buttons in the component

dialog has one, but popover should have one indeed
