When form.insert is called with a object as the default value it will submit the form after the second time it is called

Describe the bug and the expected behavior

An issue happens when inserting fields into a field list. This specifically happens when supplying a default value to the form.insert function. More specifically it seems to have a problem when the default value is an object. I can make it work if the default value is a string or number. When you call the form.insert with an object as the default value the first time it works fine. The second time it will submit the form. I have created a minimal reproduction here on stackblitz. I'm sure I could be doing something wrong but I just don't know what it could be.

Conform version

v1.2.1

Steps to Reproduce the Bug or Issue

1 - Click add again and the form submission will be sent.

[Pouet--]

I am using version 1.1.5 and it works, so it is a bug(?) introduced by a newer version.
It seems to work correctly if you upgrade to v1.2.2.

@Pouet-- That does work and I should have checked that. The reason I went back to 1.2.1 from 1.2.2 is that I'm still getting the react warning about spreading the key. I can try to work around that for now.
