MobileFrontend's Drawer component already adds a mask that covers
the whole screen intercepting any clicks to the `body` tag and as a
result handles hiding the drawer when clicked.
Therefore, this code is redundant.

This class is used for the main menu exclusively. Applying it
will reveal 2 transparent shields on top of each other when is
not desired

A new controller is added - drawers.js with methods for controlling
display and removal of drawers. The existing code in references is
moved there and extended to support scroll to hide behaviour
Console warnings will disappear with this change.
Additional changes:
* Standardise the page issues element selector - should be the container
not a link inside it (was a red link so triggering wrong behaviour)
