I have verified that this issue is no longer reproducible using Firefox Release 74.0 Build ID 20200309095159 and Chrome v. 80.0.3987.149 on Windows 10 (x64) as well as Firefox Preview 4.1.0 Build #20771637 on Android 10 (Motorola One Vision).
The right branch homepage is now accessed at account logout.
As a result, I am closing this issue.
