`isDirty` from `useField` is `true`, when you change `initialValue`, but new initial value is not set.

Describe the bug

const initialType = useMemo(
    () => getInitialType(value, chips),
    [value, chips]
  );

  const activeField = useField<DurationInputType>({
    initialValue: initialType,
  });

  console.log({isDirty: activeField.isDirty(), activeValue});

Maybe this is not a bug, but a feature, but on the first sight it looks not right. My initialValue has changed in time, what causes isDirty returned value to true, what is unintuitive because value is not changed programmatically (by setValue) or by user in an input.

This is fragment from @mantine/forms code, which is responsible for that:

// @mantine/form/esm/use-field.mjs
const isDirty = useCallback(() => valueRef.current !== initialValue, [initialValue]);

If this is a feature, not a bug, I would like to ask you to help, how I should be done.

If possible, include a link to a codesandbox with a minimal reproduction
