Problem/Motivation
Remember the page you were on and take you back there when switching Workspaces.
Proposed resolution
- Set a destination query string for the workspace button in hook_toolbar in workspace.module
- Set a destination query string for the workspace activate form in WorkspaceListBuilder
- Remove the redirect from \Drupal\workspace\Form\WorkspaceActivateForm::submitForm
- Find a way to bypass the caching of the link in hook_toolbar
