How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Enable the FF issues_list_drawer
2. Go to issues list , and view an "issue" in the drawer, the attributes should not overlap and be in single column
3. Open any work item in full view and reduce the screen size by opening the dev console
4. See that the right sidebar dropdowns open "down" irrespective of the space available
