Thanks @decherd. Tested the changes locally and they seem to be working fine 👍

I created a sister pr here which implements your change. That pr also adds a test, updates some prose, clears out the cache and re-populates it. If you like I can assign you to that pr so you get the credit for the change? If that sounds ok, I'll go ahead and merge it.

@decherd I merged the sister PR so I'm closing this pr now. Unfortunately, Github wouldn't let me assign the sister PR to you but I'll assign you in the release notes.
