This happens entirely too often for me, and the other result that ends up being focused on is "<x> \n See web results".
I've never wanted to search for anything on the web from my start menu, and to make matters worse, it always performs the search using the IE/Edge browser and Bing as the search engine. To date, I've yet to see any way of customizing (or disabling) this behavior.
If I had a list of the "most annoying things my computer does", this would certainly be near the top.
