After the recent effort to fix the error with the API removing watchlist labels from pages (T423778), I was wondering why I still occasionally see this problem sometimes. It turns out that ReFill, RefRenamer. and HotCat were removing the watchlist label by the time I get to the preview/save screen. I've already reported this to the RefRenamer script developer and it was fixed. The HotCat bug was already reported.
**Steps to replicate the issue** (include links if applicable):
* Run "Page | Tools... | Expand bare references" on any article.
* Let it process to the result, and click "Preview/Save" given there are changes to make.
* On the preview/save screen, you will see that if the article had watchlist labels associated with them, they will no longer appear.
**What happens?**:
Watchlist labels are reset.
**What should have happened instead?**:
Watchlist labels that were previously set should appear.
**Software version** (on `Special:Version` page; skip for WMF-hosted wikis like Wikipedia):
