Google using inline CSS?

With only one font-fam­i­ly? And it’s Ari­al? The nerve!

<td class=bubble rowspan=2 style="font-family:arial;text-align:left;font-weight:bold;padding:5 0"><b>Celebrating 5 years of Gmail</b></td>

I don’t have Ari­al installed, so this shows up as my default serif, because they don’t even both­er to include the gener­ic ‘sans-serif’ font-fam­i­ly.
