Steps to replicate the issue (include links if applicable):

• i open -> Temporary_accounts
• see the text starts with a temporary user name => ok the #lsth is transcluding EN contents into the EN page
• now I open similarly the FR translated page -> Temporary_accounts/fr

What happens?:

• the expected text brought by #lsth is missing in this FR paragraph :

What should have happened instead?:

• I expected the transcluded contents would be the existing FR translation of the EN paragraph
• I tried using Special:MyLanguage/ but it does not help
• I used /fr and the FR anchor value : it works but it is a harcoded way and cannot be adopted
• Where is the solution ?
