Fixed issue on blur event when strictMax is true

Hello @aaronrussell,

I've realized that when strictMax is true, there is an issue on blur event. If you keep a key pressed until the maximum characters be exceeded and press the tab key, then the exceeded text won't be dropped.

I don't know if that is really a problem, but I would like to let you know about it. BTW, great job! :)
