I have verified this issue and is no longer reproducible on the latest Nightly 76.0a1 build (Build ID: 20200331093527). I have tested this on Windows 10 x64, macOS 10.14.3 and Ubuntu 18.04 x64.

• The login item is correctly displayed and a single vertical scroll-bar is displayed when the browser is resized.
