I have tested this issue and is still reproducible on the latest Nightly It locale 71.0a1 (Build ID: 20190913092859) (64-bit) on Windows 10, MacOS 10.14 and Ubuntu 16.04 x64. The "Get your passwords on your other devices" text is still exceeding the header area.
Considering this, I will reopen this issue.

Can you please provide a screenshot?

Please don't reopen bugs unless the patch is backed out. Can you please file a new bug for the issue? I am able to confirm that at a window width of about 810px the text overflows the container. In this situation we agreed we should just hide the promotional text.

I understood, sorry for this inconvenience.
Considering the fact that the issue is still reproducible if the window is horizontally resized I have logged a new issue for this in bug 1581506

However, I have verified the changes made on the latest Nightly 71.0a1 (2019-09-15) build on Windows 10 x64, Mac 10.14 and Ubuntu 16.04 x64
