Steps to replicate the issue (include links if applicable):
- Create a page to mark for translation with the following content
<translate> <!--T:hello-world--> New translation unit! </translate>
- Start marking the page for translation
What happens?:
I see a notice stating:
No changes to review. Marking this page for translation will not edit the page nor any existing translation unit.
What should have happened instead?:
The notice should not be displayed since this is the first time the page is being marked for translation
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):
Reproducible on https://meta.wikimedia.org/w/index.php?title=Special:PageTranslation&target=User%3AAPatro+%28WMF%29%2FTestBug&do=mark
Other information (browser name/version, screenshots, etc.):
This appears to be a problem if the translation units are given unit names manually.
