Well I decided to see which of the four browsers I have installed the "New Reply" button would work with. The four browsers I tried were Dolphin HD, the default browser, Firefox, and Skyfire. Of those four only Firefox worked, and it was a beating typing this reply as the keyboards kept becoming unresponsive. I had to keep tapping outside the edit box then back in to get Swype to work. Swiftkey on the other hand would just start repeating all the letters between the cursor and nearest space. Not to mention the editbox wouldn't auto-scroll properly so if I wanted to see what I was typing I had to scroll it manually.
I do hear the click-like sould my phone makes when I click a link when I click new reply, but nothing happens using Dolphin HD.
