So obviously just as we click on the "new Google Docs"-link the JS-function

onMouseDown: function() {li(si({withAddtlText: !0}), "https://twitter.com/cyrusroshan")}

gets called, which overwrites the clipboard.

I didn't spend any time looking at the obfuscated functions li and si, but why does this have to be in a 14,000 line Javascript? Isn't writing something to the clipboard a regular html function? https://www.w3schools.com/howto/howto_js_copy_clipboard.asp
