Some carto mapbox baseline failures are fixed in #7019 today.
Please fetch upstream/master and then merge master into this pull request as well as into other PRs you have open.

The extra bold does not render properly on this branch if you view mapbox_fonts-supported-open-sans-weight mock.

Hmm, so it's not broken in the first place? Strange, i had that impression.

Ah, it's because this is a problem only after moving to maplibre, where the Extra Bold font appear completely missing, and adding this patch does render text, but it's not bold, so there is a fix needed for that in the MapLibre branch.

OK. Let's keep the patch inside the maplibre PR.
Thank you.
