Some pages show error when using browsers back button or revisiting inactive tab

Bug
1

Sometimes, when I return to a previously opened tab showcasing the leaderboard and the tab refreshes, I am taken to a 404 error page.

I see a similar behavior on my forum when I leave the /admin/plugins page open and revisit the tab later. The /admin/badges page, for example, works fine. So I connected my tablet to my computer to check the browser console. While waiting for the tab to become inactive again, I thought I could check /logs as well. And when I did that, I accidentally reproduced the bug on my computer:

  1. Visit /admin/plugins.
  2. Use the link in the admin sidebar to go to /logs.
  3. Use the back button of the browser to return to /admin/plugins.

Result:

and after you click “try again”, the plugins overview works again, but more errors appear in the console.

When you try the same with /admin/badges, it works as expected:

  1. Visit /admin/badges
  2. Use the link in the admin sidebar to go to /logs
  3. Use the back button of the browser to get back to /admin/badges

The above steps also work to reproduce the issue I noticed with the leaderboard. When I add /logs to the sidebar, visit a leaderboard, use the link to logs in the sidebar, and then use the browser’s back button to return to the leaderboard, Discourse says the leaderboard does not exist.
