Code coloring problem with a RegExp ending with a / after an ||

[erikras]

The javascript coloring is being thrown off by an escaped / at the end of a regular expression.

const addProtocol = (url: string): string =>
	(!url || /^https?:\/\//.test(url) ? url : `http://${url}`)

Interestingly, if you remove the !url || before the RegExp, it works fine. Something about the || is throwing it off.
