Hides tooltip on discussion toggle button when clicking
What does this MR do?
Hides the tooltip when clicking the discussion toggle button.
Rather than triggering the tooltip to hide we trigger blur. This is because of how amazing Bootstraps tooltips are. They are shown also on focus so if we trigger the tooltip to hide & then mouseover the button again the tooltip still shows.
What are the relevant issue numbers?
