I am hesitant to merge this without doing a quick sanity check as well, please don't take the radio silence as ignoring you! I have just been a bit busy

I will try to check this out tonight but I am OK merging it

[xconverge]

Did a quick sanity check and your investigation was very thorough!

Merging this, thanks a lot!

We will keep an eye out for new issues being reported when we do the next release, but should be good to go!

FYI your wording was close on the PR to have it do something handy

Ok, thanks for the heads-up! I just changed the title for the other open PR to hopefully utilize that Github feature.
