werid dream about javascript and doxxing

I had a dream where a website doxxed me because of something relating to javascript and password manager autofill so they could figure out what was filled in the page and automated the filling process (which is convenient with password managers, but it's basically injecting stuff into web pages and can fill names and whatnot automatically, and if the page is monitoring what is happening, or forces the autofill to occur, then it can get your name and address)

so you just do something like style="display:none;" to hide the extra fields?

but this isn't exactly what I meant, I meant javascript would somehow try to fill fields and then use your browser's autocomplete, or something

or maybe you could combine clickjacking with iframes and lastpass and DOM stuff to find someone's other account passwords

It wasn't a dream:
