👍 Thanks @atarix83 ! I've tested and verified the Shibb bug on the demo site, and installed this PR on a local (Docker-based) Shib setup and found it fixes the bug. Code looks reasonable (though it doesn't have many code comments, but I'll let that slide this time as the tests are detailed). Thanks again.
