Documentation rendering problem on tablet device.
I'm trying to read the ExtJS documentation (e.g. http://docs.sencha.com/ext-js/4-1/#!...n_architecture) on my tablet (Motorola Xoom - Android - Jelly Bean) but there seems to be a rendering problem. The end of each line is cut off with the last few characters disappearing off the screen. Scrolling/Swiping does not reveal the rest of the line.
I have tried with Chrome, Firefox and the default Android browser - all show the same problem effectivly making all the documentation un-readable.
Unfortunately the API docs are not mobile friendly at this point, they are meant to be viewed on a desktop computer.
