**Steps to replicate the issue** (include links if applicable):
* Be logged in
* Have `patrol` user right
* Visit a page listed in https://en.wikipedia.org/wiki/Special:NewPages?namespace=2
* Open JavaScript console
**What happens?**:
* `Exception in module-execute in module ext.pageTriage.views.toolbar: TypeError: mw.pageTriage.Article is not a constructor`
**What should have happened instead?**:
* No console errors
**Software version** (skip for WMF-hosted wikis like Wikipedia):
**Other information** (browser name/version, screenshots, etc.):
* Reported by @Nardog
* Appears to be intermittent. I cannot reproduce it.
* [[ https://gerrit.wikimedia.org/r/c/mediawiki/extensions/PageTriage/+/865105 | This patchset ]] is probably to blame. I made a comment about finding this during my testing. We decided to merge anyway though, because myself and @kostajh were unable to reproduce it after the first occurrence.
* Race condition?
* Appears to be purely a console error. Toolbar still loads, buttons still work, etc.
