This also removes the tooltip and instead expands the widget out while hovering
the cursor over the label.

Joined a channel on a local ergo server that had a long topic with links. Link behavior works in all cases except when text is selected which is fine. If you click some where in the label to clear the selection links work again. Also verified the hover behavior. I'm not a fan of using 10 lines as a magic number, but it should be fine for now.
