**Breaking Changes**

```js
// decodes to javacript:alert('XSS')
const vulnerableUrl =
  "&#0000106&#0000097&#0000118&#0000097&#0000115&#0000099&#0000114&#0000105&#0000112&#0000116&#0000058&#0000097&#0000108&#0000101&#0000114&#0000116&#0000040&#0000039&#0000088&#0000083&#0000083&#0000039&#0000041";

sanitizeUrl(vulnerableUrl); // 'about:blank'

const okUrl = "https://example.com/" + vulnerableUrl;

// since the javascript bit is in the path instead of the protocol
// this is successfully sanitized
sanitizeUrl(okUrl); // 'https://example.com/javascript:alert('XSS');
```
