I did a test on the latest version (commit : FEATURE: new tag info heading (#40171) · discourse/discourse@3c95497 · GitHub)
It works, but there’s a Deprecation notice
[THEME 9 'MD Topic List Mobile'] DEPRECATION NOTICE: Accessing site.mobileVieworsite.desktopView during the site initialization can lead to errors and inconsistencies when the browser window is resized. Please move these checks to a component, transformer, or API callback that executes during page rendering. [deprecated since Discourse 3.5.0.beta9-dev] [deprecation id: discourse.static-viewport-initialization] [info: https://meta.discourse.org/t/367810]
I’ll see what I can do, but it doesn’t break at least
