Incompatibility with iOS / Safari

[Carlos Valente]

Hey!

Trying to run a React App with tinykeys in iOS crashes with error "Invalid regular expression: invalid group specifier name"

I have tracked down the error to a regex in tiny keys

var n = e.split(/(?<!\+)\+/)

Is there a chance you could have a look at the issue? This is definitely a problem on the Apples side, but you know....
