Quantity increment decrements not working for grouped product magento 2

Question

As a test I created 3 simple products and associated them with a grouped product.

I enabled qty increments for the grouped product and set the allowed increment.

The system allows you to add product quantities to the cart that do not meet the increment rule.

I also tested this with a configurable product (using the same 3 simples) and in this case it worked as expected.

Does anyone know if this is a known issue? Or if there are any work arounds for it?

IS there any configuration need to be done for his through admin panel?
