[react-form] dynamicList value is reverted to default value after submit when using makeCleanAfterSubmit

[alexmic]

Overview

Using makeCleanAfterSubmit: true reverts the value of dynamic lists to the default value instead of the (successfully) submitted value.

I've managed to fix the issue locally by adding dynamicListBagRef.current = dynamicListBag; after https://github.com/Shopify/quilt/blob/main/packages/react-form/src/hooks/submit.ts#L32 but I am not sure if this is the right solution.
