Clickjacking

Steps to reproduce: create index.html file with following content: <iframe sandbox="allow-scripts allow-forms" src="https://go.pushwoosh.com/register" width="1000" height="600"></iframe> Open index.html in browser Actual result: Pushwoosh viewed in iframe. Expected result: do not allow clickjacking Root cause: ``` var isInIFrame = (function () { try { return window.self !== window.top; } catch (e) { return true; } })(); ```
