The CMS12 Commerce Catalog Menu with the class oui-vertical-tab stage__item__content--column doesnt seem to hide so is always visible to the users.
In our business case we have users that only use the commerce UI and having this open does reduce the amount of area they have to use. Also in Our use case we are using Avensia storefront to connect to D365 so we are not using the in built catalogs menu at all so this constantly being open is also not needed and unwanted.
In the CMS site the epi-side-bar-navigation is auto hidden as you would expect.
