Similar to T209249, except now the other link is not a redirect (the page hasn't been created), but a variant that is correctly linked to the disambiguation page without needing to create a redirect.

The problem can be seen on the following pages on zhwiki:

• Link to "势" (simplified script, dab page) has mw-disambig, which is correct
• Link to "勢" (traditional script, non-existent page) does not have mw-disambig. (The link correctly goes to the page "势". Zhwiki has no page titled "勢".)
• When both links are placed on the same page, even "势" loses its mw-disambig.

What happens?:
"势" does not have mw-disambig when next to "勢".

What should have happened instead?:
"势" should have mw-disambig.
