Summary:
Back button does not work as expected when a user clicks "View in Context" option of a Calendar Event selected to be reviewed

Steps to reproduce: 

1. Navigate to Control Panel > Workflow > Process Builder > Configuration and assign Single Approver workflow to Calendar Event
2. Go to main site > select "+" on the top-right menu > Widgets and add a Calendar to the main page
3. Click on "Add Event" > add a title "My Event" and click on "Submit for Publication"
4. Click on Profile menu available on the top-right of the screen > My Workflow Tasks > Assigned to My Roles > "My Event" > Click on View option (eye icon) > "View in Context"
5. Click on the back icon next to CALENDAR and observe the behavior.

Actual result: The page remains in "View in Context" scenario
