Doesn't work after updating to React 16.5

[dmlukichev]

Warning: The <ReactCursorPosition /> component appears to have a render method, but doesn't extend React.Component. This is likely to cause errors. Change ReactCursorPosition to extend React.Component instead.
Uncaught TypeError: Cannot call a class as a function at _classCallCheck (ReactCursorPosition.js:3)

Problem lies with more strict rules for class call check in latest react version. Because of this old versions of react-cursor-position stopped working work.
They already released new version with fix, but since react-image-magnify uses old one we still have this problem.
Updating dependency will solve this issue.

I hope it will be closed pretty quickly.
Otherwise you can resolve it temporary by directly editing package-lock.json and setting proper version there.

        /* ... */
