Google Testing Logo Sizes in Search Results?

Philip Lenssen over at Google Blogoscoped noticed a variance in the size of Google logos in the search results from browser to browser.

I did a little experimenting and noticed the same thing. On Firefox and Safari, the Google logo is proportionately smaller than on IE and Chrome for me. Check out the images below.

Anyone else seeing the same thing?
