steps to reproduce: 1. Load https://marketplace-dev.allizom.org/en-US/app/seevans-underworld-adventur/ on fennec nightly on your Android phone 2. Click on the < in the breadcrumb to go to the homepage reproducible? sometimes observed behavior: Sometimes, clicking on the < in the breadcrumb doesn't load the homepage

Only a mobile bug. We should keep an internal stack of the history since we can't tell from `popstate` whether the user went forward or backward.

Not sure how much work this is, but marking p3

I can make this consistently happen after clicking app photos (..and the lightbox appears). Get to the detail page, click a photo, close the modal, click "<", doesn't go to homepage.

I'm going to fix this by just doing history.back(). I wanted to keep an internal stack so that when I go from Detail Page -> Reviews -> Submit a Review -> Reviews that the back button on the "Reviews" page goes to the "Detail" page. But maybe that's too complicated. history.back() might be dece enough.

The new designs don't have this. Assigning to Davor so he can RESOLVED FIXED this when the new header lands.

Fixed this in the gaia-ui branch.

Works on gaia browser only. Hopefully new designs won't have this issue.
