issue: Controller rules.pattern doesn't apply new value without explicit undefined

[PetrBorisov]

Version Number

7.51.3

Codesandbox/Expo snack

https://codesandbox.io/p/sandbox/thirsty-goldstine-n9rfhv?file=%2Fsrc%2FApp.tsx

Steps to reproduce

1. Go to codesandbox example
2. Type "message" into input
3. Click "switch pattern" button
4. Type "message" into input
5. See error

Problem here is that after click on "switch pattern" I start to provide rules = {{ required: true }} property to controller without any explicit undefined for rules.pattern and Controller use "cached" value from previous rules property value

---

Workaround 1

rules={{
  ...rulesToUse,
  pattern: rulesToUse.pattern,
}}

---

Workaround 2

const rules2 = {
  // pattern: undefined,  <---- uncomment this line
  required: true,
};

---

P.S. I didn't try to catch same behaviour with register({rules}) maybe it's not a Controller specific behaviour

Expected behaviour

I expect that change of "rules" property will update rules.pattern property as well without explicit "undefined"

What browsers are you seeing the problem on?

Chrome

@bluebill1049 I know about workarounds, but rules.pattern is not marked as deprecated and has this bug
