alpine devtools fails when x-data is on a <form> element
I encountered the following error, I think it's from x-data being on a <form> element:
Uncaught DOMException: Failed to execute 'postMessage' on 'Window': HTMLInputElement object could not be cloned.

When I moved my x-data from the form to a parent element the error went away & everything seems to work.
I assume if this is the case, it could be some sort of privacy reason with html forms. I'm ok with my workaround either way, feel free to close.
I'll have a look, thanks for reporting this issue.
I have encounterd this same error recently, it seems to be as above when the x-data is on the form tag AND you have an input field with the name="id".
If you change the name="id" to anything other than id then the issue goes away....?
