I hate that feature with an intensity that's hard to describe.

I know you can press it again or something but for the love of $deity don't fuck with the defaults.

That said I'm equally angry my browser so happily allows this.

Sure if it's a proper web application like OnShape then sure, override default key bindings, but ask me first and remember my choice. If I say no then just don't feed those keystrokes to the webpage.
