This occurs even in incognito mode though.

Incorrect. Incognito mode does not use the search provider's autocomplete results.

Interesting. I hadn't noticed that, but you are right. I only get suggestions for searches I've made during my incognito session (so stored locally in the browser's memory) or for pages in my history for that session.
