How can I enable mouse scrolling in tmux without also enabling mouse selection?

Question

I currently use set-window-option -g mouse on, but this also enables selection inside tmux with my mouse. I'd like to disable this behavior but still keep scrollback working. Is this possible?

You can unbind the MouseDrag1Pane key in the root table to prevent tmux entering copy mode when you drag, for example:

unbind -n MouseDrag1Pane
