Hi, it seems that with R-B 1.0.2021 (Build #21420607 GV: 78.0a1-20200519094847) the issue has been fixed. Verified with Google Pixel 3 XL.

I'll reopen the issue it reproduces when accessing article from Morning Brew or Medium Daily Digest but not when using for example : https://firefox-ci-tc.services.mozilla.com/tasks/index/project.mobile.reference-browser.v3.nightly . When going to latest, returning and then tapping on the forward button.
