Our cookie 'storeid' needs a value for the SameSite attribute

[MyPyDavid]

Description / Beschreibung

Currently, in my local debug environment I get a warning in the Mozilla Development Browser about the SameSite attribute:

Cookie “storeid” does not have a proper “SameSite” attribute value. Soon, cookies without the “SameSite” attribute or with an invalid value will be treated as “Lax”. This means that the cookie will no longer be sent in third-party contexts. If your application depends on this cookie being available in such contexts, please add the “SameSite=None“ attribute to it. To know more about the “SameSite“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite

Before I got the CSRF token error in Chrome and thought it was related to the cookie warning, see https://github.com/js-cookie/js-cookie/issues/846 for example.

Expected behaviour / Erwartetes Verhalten

• our cookie storeid should not get any warnings and get the appropriate attributes

Context / Kontext

Local Debug, 2.1.2
