getOrigin issue within iFrames

[sntk]

Reporting a Bug?

Yes.

react-image-lightbox/src/util.js

Line 35 in c9fcb5b

const getOrigin = href => href.match(/(.*\/\/.*?)(\/|$)/)[1];

Requesting a Feature?

No.

I'm using this component inside a Chrome Extension (in an iframe), the document.referrer returns an empty string which throws a typeError

Uncaught TypeError: Cannot read property '1' of null
    at getOrigin (<anonymous>:1:58)
    at <anonymous>:1:35

Would it be possible to add a check for empty strings?

Much appreciated!

This may not be the most elegant solution, but perhaps

const getOrigin = href => href.length ? href.match(/(.*\/\/.*?)(\/|$)/)[1] : null;

Thanks for reporting, I have exactly the same issue inside my Storybook environment.
