What is a potential risk of passing a partial data object to setData?

Explanation:
Passing a partial data object to setData can replace the entire stored data with only what you provided. If setData overwrites the current object, any fields you didn’t include will be removed, leading to data loss. To prevent this, merge the partial update with the existing data (for example, spread the current data and then apply the new values) or use an API that supports patch/update semantics rather than a full replace. This keeps untouched fields intact while updating only the intended ones.
