In the above example the user saw they were on an Org A page and clicked Create intending to create an article in Org A, but sometime after they loaded their Org A page their “current tenant” session variable had been switched out from under them by a different tab.

One solution is to always pass the intended org along in the POST, but requires something disciplined and nesting POST /org/A/articles is one way to do that.
