I can't actually sign in on Android devices

I tried this both on my local install and hoodie.ydns.eu

I can click the down arrow, which presents me with the three options, but I cannot actually click Sign In.  This makes me sad because I think hoodie is just right for me, but working on Android browsers is absolutely essential.  It should make you sad because it's not a good first run experience for people trying out hoodie.

I tested this both on my samsung galaxy s4 google edition (which runs some 4.4 I think) and my Samsung Note 2014 tablet.

@gr2m wanted a ping on this issue.
