While browsing Stack Overflow on my mobile device, I've stumbled upon the cropped hamburger icon to toggle the communities list. However, this is not limited to my phone and seems to be the same for most of the other sites in the Stack Exchange network as well.
I'm not sure if this is intended or not, but compared to the iOS app it doesn't seem to be right. The hamburger icon in the app is not cropped and has lots of space to the left side, so I just wanted to report/discuss it on Meta to let you know.
You can see the cropped hamburger icon (
.icon-hamburger in CSS) in the screenshot (taken via Chrome Developer Tools) below.
