[Bug]: Marking a document as favourite in Writer doesn't sync to Drive's Favourites tab

App

Writer

What happened?

Marking a document as favourite from the Writer navbar (⋯ menu → Favourite) doesn't sync with Drive. The star appears to toggle in Writer, but:

• The document never appears in Drive's Favourites tab.
• Reloading the page reverts the favourite state — it isn't persisted.

Steps to reproduce

Open any document in Writer.
Click the "⋯" menu in the navbar → select "Favourite".
Reload the page — the star reverts to unfavourited.
Go to Drive → Favourites tab — the document isn't listed.
