I think my sequence of operations was:

Open Tofino.
Click a link in history.
Cmd-T, reddit.com.
Cmd-T, enter a search.
Cmd-2 to select reddit.com.
Click a link.
Close the reddit tab.

warning.js:36 Warning: setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the Search component.
