Anything that require stdin breaks the term.js shell in maximized state on Mac OS

[bitspook]

On Mac OS I had to install tty.js by chaning pty.js dependency to latest commit:

    "pty.js": "https://github.com/chjj/pty.js/archive/18238d37e2915b3ac97e4ae0d5cb3e33f76ac758.tar.gz",

Everything else works fine, but when the terminal window is maximized (by double clicking the top bar), and I run something like less, vi, or emacs from it, it breaks the terminal. Everything goes away leaving a grey background.
