meta.dirty never becomes true when a field is initialized with undefined

[Nodios]

What happened?

This is "copy" of #5033 because it still does not work. I see the OP closed it with duplicated issues however it still does not work. Please see reproduction code: https://stackblitz.com/edit/vitejs-vite-huj1m5qm?file=src%2FApp.vue

Observe that in the initial values, value of "test" is set to undefined. In that case, dirty is not changed as expected. If you change the initial value from undefined to an empty string, it works as expected.

Reproduction steps

1. Open the Stackblitz link
2. Type anything in input "Person name"
3. Observe form dirty remains "false"
