Yeah, I just tried to select text in the button element and translate it specifically or copy it, and it doesn't work. You can highlight it, but you aren't selecting the text.

This is what is copied from the login page, you can see that the button text is missing:

Login

username: password:

Forgot your password?

Create Account

username: password:

My fault, I didn't try to copy! I can still select, but sorry for not checking if copy is possible! From your other reply I noticed this!

But yeah, HN isn't the best in this regard :)

Maybe dang will one day consider changing to <button>reply</button>!
