@Dogu can you check whether all users get Codex message styles in this mode?

https://en.wikibooks.org/wiki/Indonesian/Grammar/Adverbs (a wiki using this mode) doesn’t seem to look so for me logged out or logged in. The message lacks Codex styling.
https://fi.wikipedia.org/wiki/Kaukopuhelu?safemode=1 has the same issue.
On https://fi.wikipedia.org/wiki/Venäjän_vaakuna?safemode=1 the Codex styles load after the page gets loaded.

Hi @Ladsgroup, Just to remind you to deploy the change.

My apologies. Start of the week was quite busy. I get to it now.

This is how it's going to look like (it's English because my interface is English):

If you don't like this, this week the new updates will come and the old "simple ui" will look much better. We can revert to that later in the week.

The only problem seems to be that on pages like https://ru.wikipedia.org/wiki/Северная_Македония_на_«Детском_Евровидении» Codex styles get loaded after the page gets loaded. Otherwise all good.
