With reference to the email thread: https://lists.CentOS.org/pipermail/CentOS/2017-October/166709.html

Can we have the 32-bit Wine Gecko package(s) built and published to the repository: https://harbottle.gitlab.io/wine32/7/i386/

Seems like someone has already built wine-gecko-2.47-alt2.noarch.rpm

At the moment, I have to click on the ‘Install’ button the first time Wine detects missing Gecko while viewing an Application’s Help.
