Why does the layout in Link Detox Screener look broken?

The layout can be broken because, in order to protect you from potentially malicious sites, the Link Detox Screener loads the pages in a sandboxed iframe.

Some sites do not allow resources like fonts, CSS, images or Javascript to be loaded from such iframes.

In that case, sensitive browser data like session storage, local storage, and cookies will not be loaded. But don't worry, as you can rest assured that malicious sites will not affect any of your sensitive data due to the sandboxed environment the Link Detox Screener works with.
