JavaScript URL Issues in the latest version of Brave Browser

## Summary: * The URL javascript: can redirect users to any site, instead of executing JavaScript. ## Additional Notes * Found as partners by @kicker (http://hackerone.com/kicker) and myself (@smelt). ## Products affected: * The current version of Brave Browser on Windows. * The current mobile version of Brave Browser. ## Steps To Reproduce: * Open Brave Browser * Go to javascript:javascript: or javascript:javascript:hackerone.com in the Brave Browser. * If using the **javascript:javascript:** link, the browser should redirect to your search engine's homepage. * If using the **javascript:javascript:hackerone.com** link, the browser should redirect to HackerOne. (HackerOne was just an option, you can redirect to any URL.) * This bug is different than the redirection bug previously disclosed, allowing addresses after @ to redirect to that site. The site can be redirected using simply the javascript: URL in this bug. ## Supporting Material/References: * See attached video files. Thanks for reviewing this report, and let me cross my fingers, that it's not a duplicate! :)
