Bug: Empty project after refresh in full-page story when it was deleted by different user

When the user has opened a full-page story and somebody else deleted this ticket, after a manual refresh of the full-page story user sees an empty project.

Steps to reproduce:

1. Create a new story

2. Copy link of story

3. Open story in new tab to have (full-page story)

4. Delete the story in different tab

5. Refresh tab with the full-page story

Also, when a user opens that URL after deletion, the user can see 404 page. It would be nice to open that project with a dialog “Story was deleted”.
