Was just pointed to #3325 which raises this exact issue – seems it was closed erroneously

@mhart Please run npm run add-change to add a changelog entry for bugfix for this PR

@trivikr it would be great if the CI process could do that – would save ppl having to actually clone the repository locally, install everything, etc.
