"Press Tab to search <site>" in Chrome not working

The problem

After partially entering a URL like meta.st, Chrome adds in the rest of the URL highlighted in blue and says "Press Tab to search Meta Stack Overflow". But on pressing, instead of showing a blue box and allowing us to search on that site, it just moves the cursor to the next item like in a normal text-field.

Other info

I'm on Windows 7 Home Basic. My Chrome version number is 22.0.1229.52 beta-m (beta channel). This was working before.

What I've tried

I've reported it in Chrome (by going to Options > Tools > Report an issue...). I've also tried deleting all my custom search engines (they might've been interfering) and also tried creating a new profile. I also googled, but to no avail.

How do I fix this? Thanks.

Solution 1:

The problem went away on it's own. Everything is working as expected. As a side note, they also changed the UI of the prompt that comes up.

As @HumanBlade postulated, it was probably just a bug or regression. I guess such things are to be expected if you're using the Beta or Dev channel.

Anyway, considering Chrome is self-updating, this question is probably too localized and will get closed very soon. Cheers till then :)
