Backspace on wide keys jumbles input

[freemaths]

With a key such as "sin" backspace jumbles the characters of the preceding string. E.g. pressing:

sin sin {b}

result in

nsi

Hi @freemaths!

Wow that is odd... to be 100% honest I had no idea that restrictInput would remove blocks of letters like that LOL. And I think that is where the problem is located. I'll try to dig into the code more tonight. Thanks!

I found the problem! The fix is now available in the master branch.

I updated the demo so you can test it, but rawgit is taking a while to catch up so don't think it's broken just yet 😉

Ok, now it's working... I think it's sort of a bonus that if the caret is in the middle of a word like c|os and you press sin, the cos gets replaced with sin.

Works perfectly - many thanks.
