Behavior of Enter key when pressed in address bar

Question

I have a link like this: http://....../index?spid=1#tid=2&cmno=17 which will render an index page and move window position to top of the comment no.17 (cmno=17). It works normally.

But in other browser like IE, Firefox, when I was in that page, and focus mouse on the address bar then press enter again without changing URL, the page does not refresh. While in Chrome, when I do the same thing, the page is refreshed.

Is that normal behavior and difference between Chrome vs IE, Firefox? Or it's just my website's source code problem? Please help me.
Thanks a lot.

I asked chromium and this is the answer:

So it is intentional UI design.
