Steps to Reproduce
The storefront API cart mutations return cart, userErrors, and warnings. See the documentation for cartLinesUpdate for example.
The applicable queries in react-hydrogen do not return userErrors or warnings, instead returning only the cart based on the specified cartFragment. See the CartLineUpdate mutation for example.
This means there is no way to display userErrors or warnings as these are effectively swallowed by react-hydrogen. This is confusing for the user as the cart may be updated in a way that is not consistent with what the user requested without any feedback being displayed to the user.
Expected Behavior
userErrors and warnings are surfaced by react-hydrogen so these can be displayed to the user.
Actual Behavior
userErrors and warnings are swallowed by react-hydrogen.
