`append` function of `useFieldArray` and `isDirty` on form state does not work as expected when nesting forms

Describe the bug When having nested forms, it looks like the context of the append function of useFieldArray gets messed up. Therefore isDirty on the form state stays false after appending a field to the field array, even though dirtyFields have been populated (Example 1).

If i wait for the nested form to get removed from the dom, the append function works as expected again (Example 2).

To Reproduce Steps to reproduce the behavior:

For Example 1:

1. Type any string into the text field in the modal on the bottom right
2. Press ‘Submit’ in the modal on the bottom right
3. Now you see in the dumped form state, that isDirty is still false, but there are dirtyFields

Expected behavior

1. append should work correctly, even in nested forms
2. isDirty must be true, when there are dirty fields / when a field has been added to a field array
