When a link is shared in chat and it ends up in a specific position on the screen it is impossible to click it (without fiddling with the DOM).
As you can see in the printscreen above a link is in a post at the end of the line. However when I try to click the link the post options overlays the link (once I hover over the post):
- Link to transcript: http://chat.stackoverflow.com/transcript/message/12993943#12993943
- Resolution: 1366 x 768 (laptop)
- Browser: Chrome v3300 (by the time you read this it will be at that version)
