M2.4.6: Cannot update price after changing tier price for product

ISSUE:

 If product is exist in cart and we change tier price for the product then on cart reload price is not updating. It is not working on default Magento 2.4.6-p3 as well as in BSS MSVP demo site as well please find the attached video from demo site.

Reproducible steps : 

1/ Set Tier Price for Store view

2/ Add that product to the cart [Here price is showing which we have set for store view]

Using add to cart rest API

POST : {{url}}/rest/{{store_code}}/V1/carts/2277/items/

{    "cartItem": {        "sku": "24-MB01",        "qty": 1,        "quote_id": "{{quote_id}}"    }}

3/ Now change the same tier price

4/ Just Reload the cart

GET : {{url}}/rest/{{store_code}}/V1/carts/{{quote_id}}/totals

{{url}}/rest/{{store_code}}/V1/carts/{{quote_id}}/totals

Current Behavior: Price is not updating on reloading the cart.

Expected Behavior: Price should be updated on reloading the cart
