Actual result

  • The final tab is not open.

  • will provide one asap;

Additional notes

  • recording with the issue: link
  • even if the page is not fully loaded it would make sense that after the restart the link to still be there
Has Regression Range: --- → no

This would happen when sessionstore hasn't had a change to flush the latest changes to disk, thus the state being incomplete when restarted. Not sure how to fix that - there's always going to be a window of time between opening the last tab, flushing to disk and a crash.
So I think this bug may end up being a WONTFIX.

As per the discussion with Mike on Slack, marking this bug as WONTFIX; it is a really edge-case scenario to begin with.
