Same for me in Firefox (on Windows 8.1); it seems to be at about 2010 pixels that the text stops falling off the right-hand edge.

Works OK for me in both Chrome and IE. Also works OK for me in Firefox on Android, at a couple of different widths.

If you open it in Chrome, you can try disabling JavaScript on the site with the lock icon. This is the default for me, seems it doesn't load the header image this way but that's fine.

I worked around this with "reading mode".

It happens on Firefox, but not on Chrome for me
