Misspelled words are not shown as such.

Got it to work in the console and started trying random words, and I'm getting the wrong results.

checker = require('spellchecker')
checker.isMisspelled('helo')
> false
checker.isMisspelled('hel')
> false
checker.isMisspelled('hello')
> false
checker.isMisspelled('helasdfasdf')
> true

Cheking the en_US.dict file I can see those words don't exist, but both hel and helo are suffixes for words that do exist in the dictionary.

I'm also seeing this. Everything is spelt correctly which is great for my bad spelling but bad in terms of functionality. I'm using osx, electron 1.2 with en_GB. I think this could be related to #49
