What happens when a Product without variant is changed to have a variant? What will the quantity go? What happens when a Product without a variant is returned as a variant?

1. Case 1

   1. Create a Product Template with no variants, then add the Quantity. Wrote down the result

2. Case 2

   1. Create another Product Template with no variant, then add quantity

   2. Then add variants (at least 2),

   3. Then check the previous quantities, where those will be going

   4. STEP 4 (Buying the variant)

   5. Remove the variants, check the previous qty

      1. They are still there
