The first letter in this message isn't capitalized.

Your description only mentions older mocks -- do you have mocks for this
version?

Thanks for catching :) This is an illustration of how the design kept changing
while I was writing this CL.

These slides
https://docs.google.com/presentation/d/1k4_lZEnXn2e-U_3BQwvdZvtge3Jgld3bNM-do...
were OK'd by the UI review. They already show the non-capitalized options. The
dropdown should now look correctly, except that it uses the same popup
background view as other dropdowns in Chrome (slightly less fancy and
material-designish than in the mocks). IIUC, this is android:popupBackground
that is set globally in styles.xml, so in the end we decided not to override it
for this particular instance.
