Thanks for this fix @troelslenda - the main fix and the tests look great. Could you remove the additional refactorings that were added (i.e. the addition and removal of parentheses, and the reformatting) since they are not relevant to this fix.

Hi @petebacondarwin!

Thank you for your quick response. I've cleaned up the PR with a git commit --amend.

[petebacondarwin]

Great! Thanks.
Unfortunately, your amended commit message is all on one line, which is breaking the lint checks.

Hi @petebacondarwin
It should be good now. No failing tests it seems
