From the chrome bug[0] it seems like this was changed to work without a gesture because the new tab page needs to copy text for a Google Doodle...
So instead of changing their new tab page to require a gesture like all other sites... they decided to allow any website to copy text into the clipboard. Nice.
I think copying into the clipboard needs an overhaul—even with a gesture. Don't you hate when news sites add a "- from XYZ" to your clipboard? That shouldn't be possible. I'm not sure how you'd fix this, but it should be fixed.
