Browser navigation does not work with gatsbygram

[sedubois]

• visit https://gatsbygram.gatsbyjs.org
• click on a picture
• hit F5 -> image displays in standalone instead of overlay, OK
• hit the back button -> URL changes back to https://gatsbygram.gatsbyjs.org but page doesn't change

It's a different problem. We're not waiting for the page component to load when clicking the back button so it errors (check the console). Try following steps above but then clicking on "Gatsbygram". That works.

I'll be doing a refactor of of our runtime later this week and will make sure this gets handled.

Thanks for the very clear bug report!

This is fixed now. Thanks for reporting! Hadn't noticed this tricky but fairly common edge case.
