This userscript improves the Snapchat web experience by disabling screenshot prevention features which don't prevent screenshots but do actively harm the usability.

This userscript makes Snapchat web more usable by disabling the their ill-guided attempts to prevent screenshots by monitoring control keys and tracking focus. These attempts by Snapchat do nothing to actually prevent screenshots, which they document as not being prevented, but they do actively harm the user experience. For example, say I want to reference my friend's trip info while in another browser window. When the page isn't focused the content is hidden.
This userscript just disables all that. It intercepts and blocks modifier keypress events and sets `document.hasFocus()` to always be true. This makes Snapchat web much more usable.
