Context

With the current implementation of the tab system (async tabs), every form action only refreshes the tab currently viewed. This approach is not compatible with the following edge case: deleting the current location. The user will stay on a location that does not exist anymore. The system does not handle redirection yet. That's why deleting the current location was disabled.

Story

Delete the location currently viewed

Given I have multiple locations in the ‘Content locations' table
When I select the current location
Then the delete button in the table header is enabled

Given the delete button in the table header is enabled
When I click the delete button
Then I see a modal window to confirm the deletion
And on Confirmation, I am redirected to the main location
And on Cancel, the modal window closes
