Is Google Trying Deferent Ads Format?

Is Google doing an experiment with deferent Adsense Ads Format? Yesterday I noticed ads where the Link Title is in Regular format (usually bold) and it is in Italics. (See the Picture) I have not seen this type of Google ads before.

This type of format doesn’t look fair at all. Specially it is hard to read if the Title is in Italic format. If Google increase the font size of Link Title and still keep the Bold Text format that would be more attractive.
