Vertical widths of containers removed (#24184)

A vertical overflow appears in Firefox 112/MacOS 12.6 when the system
setting for scrollbars is to "Always" show them.
--- 
Here, the fixed 100vw container widths are removed, which removes the
overflow. It is, however, only simulated in Developer Tools in latest
Firefox and Chromium, so please test on a Gitea installation.
