Network errors on session timeout when using SSO

One of the requirements of this integration is that we need to implement a short session timeout to match the main site. Currently I have the maximum session length set to Discourse’s minimum of 1 hour. It seems like setting this does work and the session does expire, however, the way this interacts with the SSO feature seems to be a bit broken – if I leave my browser tab idle for over an hour, coming back and clicking on any of the links (such as “Top” or “Latest”) results in a network error:

I believe this is a known issue, perhaps @sam can offer some thoughts.
