It seems that also backspace go one page back in history but only in IE, in Edge it work fine.

the problem was that when calling keypress insert was called that was calling redraw that was using visibility: hidden to make rendering faster. In IE and Edge when textarea was hidden it didn't prevent default behavior of scrolling the page. First try was setTimeout 0 but it didn't work (the solution was good but there was bug in debug code that was later removed when looked at diff).

Maybe there is better way to hide the cmd but don't hide textarea so it don't loose focus. In Chrome textarea keep having focus when cmd is hidden.

TODO: remove current code and add wrapper for prompt and lines, hide the wrapper instead of .cmd.
