Huge Titles in Google Mobile Search

Google's mobile search interface has a new feature that makes titles bigger for search results that have sitelinks. For example, when searching for [amazon prime], the title of the top result is so big that it can't even be fully displayed, even if it doesn't have so many characters: "Amazon.com: Amazon Prime (One Year Membership)".

Here's the same search result, but for a slightly different query: [amazon prime membership].

I tested this for various navigational searches like [microsoft], [htc], [tesla], [stanford] in Google Search for Android, Chrome for Android and iOS and Safari for iOS.
