1-3073: close sidebar when you click a link within it (#8763)

This change makes it so that the project status sidebar will close
when you follow a link within it. We do that by using JS event
bubbling and attaching a handler on the modal parent. We can listen
for events and check whether the target is an anchor and, if so, close
the modal.
