Steps to replicate the issue (include links if applicable):
Add a link to a non-existing file on a wiki page; render it with and without Parsoid.
Current example: https://en.wikipedia.org/w/index.php?title=User:IHurbainPalatin_(WMF)/sandbox&useparsoid=0 vs https://en.wikipedia.org/w/index.php?title=User:IHurbainPalatin_(WMF)/sandbox&useparsoid=1
This is also currently visible on https://pt.wikivoyage.org/wiki/Eti%C3%B3pia
What happens?:
The legacy parser link is a red link pointing to Special:Upload.
The Parsoid link is a blue link pointing to Special:Filepath.
What should have happened instead?:
The Parsoid link should be a red link pointing to the same target as the legacy parser.
Other information (browser name/version, screenshots, etc.):
From a perfunctory test, this triggers both with and without Commons integration.
