Is it expected that enabling “Modernize Foundation theme” in a Discourse forum’s “Upcoming changes” will affect the forum’s theme when that forum is not using the Foundation theme?
My forum has a lovely custom theme that was crafted by the Discourse team. We are very happy with the theme as it is. I enabled the “Modernize Foundation theme” in “Upcoming changes” today because I am trying to make a general habit of intentionally introducing the upcoming changes rather letting them later get rolled out automatically. However, I didn’t expect it to have any effect. However, it did result in various changes, such as the removal of gray backgrounds from buttons.
Maybe our custom theme inherits some things from Foundation?
