In iTerm2 Command Click on URLS does not work when inside a tmux session When not inside a tmux session, Command-Click on URLs works flawlessly.

How can I make links clickable in iTerm2 when inside a tmux session?
When hitting Command the mouse pointer changes to the  icon, but when clicking on an URL, nothing happens.  

Note I have the following settings inside my .tmux.conf 

[...]
# Enable mouse mode
set -g mode-mouse on
set -g mouse-resize-pane on
set -g mouse-select-pane on
set -g mouse-select-window on

# Mouse pane switching
set-option -g mouse-select-pane on
[...]


Disabling them and then reloading .tmux.conf does not resolve the issue.

iTerm2 Version is Build 1.0.0.20140629
tmux -V 1.9a
To use the normal mouse behavior in tmux you have to keep alt pressed. So click on the link while pressing cmd+alt. The same applies when selecting text.
