Steps to replicate the issue:

• Create a new wish on the Community Wishlist or edit an existing one.
• Try to apply some formatting to the wish title using the DISPLAYTITLE magic word (for example {{DISPLAYTITLE:''{{FULLPAGENAME}}''}} to make it cursive).

What happens?:

DISPLAYTITLE does nothing.

What should have happened instead?:

DISPLAYTITLE works as intended.

Copying a comment on this by @MusikAnimal on Talk:Community Wishlist:

The extension itself sets the display title (hence why we are able to have the wish title there), so I'm not sure it's possible to override it. For your case, I would just recommend putting quotations around "In other projects" to give it emphasis. Merging a display title defined in the wikitext with our own may be possible, but my guess is it's likely not worth the code complexity.

Still bringing this here as I believe more discussion might be useful. Feel free to close otherwise.
