Bacon seems to skip a page (?) and hide my errors

When I run bacon check, bacon seems to output things (the "computing" phase) and then skips a page.

I cannot go back to the previous page when I press "up"

To avoid that issue, I can smash up during the computing phase, and then I can stay on this page.

It seems odd that a bug like this could make it to bacon, what's happening ?

Start by reproducing the issue with `bacon check`, pressing Up during and after the “computing” phase, and observe the page history and hidden errors. Trace the terminal page/navigation handling around that phase; done means the previous page remains reachable and errors are visible without timing-dependent key presses.
