Steps to reproduce:
There's something quite strange about the auto completion in the location bar that isn't quite right. I would ordinarily expect an autocomplete to go for the "shortest valid completion based on the current prefix", to give something resembling what I think a user would expect.
A good example - I type "redd" to look for reddit. I see two top hits:
Having the homepage here as top recommended hit seems right.
I now tap the right arrow key, to see what it suggests when I accept reddit.com, and I see this:
This is unexpected, and feels like a big massive leap of an "over-fit". It might be because this one page has somehow been deemed a "top site".
Let's try it again, but put /r/a after the TLD - my thinking is it should surface /r/apple or something similar, but nope:
Expected behavior:
I would say when pressing the right arrow key or doing anything else to move forward in the autocomplete, the expectation for the top suggestion should be the shortest textual completion - "/r/apple" is a shorter completion string than "/r/apple/comments/blahblahblsomerandomthread", so the former should always be the first recommended autocompletion, as people are more likely to find a less-specific recommendation saves keystrokes.
