Can't decrease qty in cart The requested qty is not available

[Harpreet-StreamMarket]

Preconditions and environment

Magento version => 2.4.4

Steps to reproduce

1. Admin - Create a product with Quantity more than 1. ex: 20 (Catalog - Products - Add New Product)
2. Front-end - Login as Customer - Add the Product to Cart with Quantity say ex: 12
3. Admin - Edit the Product - Update the Quantity say ex: 10 and save. Or purchase the Product using other customer Id's so that the stock Quantity available is less than 10
4. Reindex and clear cache
5. Front-end - Login using Customer Reload the Shopping Cart page
   error messages: "The requested qty is not available" are getting displayed to the user. That is fine and correct.
6. Now Customer decrease the qty at the cart by setting the qty to 5 and press update button. The update does not work and it throws this dialog: Attention The requested qty is not available. So it seems impossible to change the qty smaller in cart.
7. Currently only solution is to remove product from cart and re-add it with qty 5 to cart at the product page.

Expected result

Customer update cart with smaller qty successfully

Actual result

The error messages: "The requested qty is not available" are getting displayed to the user when he tries to decrease the qty.

Additional information

PHP version => 8.1.7
Disable Magento MSI
