Short Description of the PR

The multi-tab cart-sync feature wouldn't work in a multistore-environment with disabled storeViews.commonCache feature as the keys in local-storage are prefixed with the store-code like de-shop/cart/current-cart.

Hello @cewald ,
it looks very promising. However, could you please rebase it and target to the 1.12.3? We would apply support for multistore for this very similar one too: https://github.com/vuestorefront/vue-storefront/pull/5352/files which is one the 1.12.3

I've opened up a new PR #5732 using hotfix/v1.12.3 as base branch – I've also updated the code.
