Not able to save product with attributes with - stock quantity

PrestaShop is a popular e-commerce platform that allows users to create and manage online stores with ease. However, like any other software, it is not immune to bugs and issues. In this article, we will discuss a specific bug that occurs when trying to save a product with attributes that have a stock quantity of -1. We will explore the steps to reproduce the bug, the expected behavior, and the possible solutions.

Before we dive into the details of the bug, it is essential to ensure that you have met the following prerequisites:

You have read and accepted the project's code of conduct.
You have searched in existing issues and found no previous report of this bug.

The bug occurs when you have a product with 3 attributes, one of which has a stock quantity of -1. When you try to change the quantity of another attribute from 5 to 6, you receive a message stating that you are not able to save. However, if you change the attribute with -1 to 0 in quantity, you are able to save. Moreover, you can now change this attribute back to -1 and save.

The expected behavior is that you should be able to save the product without changing the quantity from -1 to 0 and then back to -1. The system should allow you to make changes to the product attributes without encountering any errors.

To reproduce the bug, follow these steps:

Go to the product "Hummingbird printet t-shirt" and change one of the attributes to -1 and hit save.
Go to the catalog-products and edit "Hummingbird printet t-shirt". Change one of the other attributes and hit save. This is not possible.
Change the quantity from -1 to 0 and you are able to save.
