+Subject: [PATCH] gdk/wayland: Mark matched settings from the portal as valid
+
+Commit e6209de9625 added some checks on TranslationEntry.valid in
+order to figure out whether using the new font settings or the
+old g-s-d ones. However that's only set in the non-sandboxed case.
+
+This makes sandboxed applications fallback to the old (and also
+non-existing with modern g-s-d) settings, possibly resulting in
+ugly defaults being picked.
+
+Fix this by also marking TranslationEntry elements as valid when
+using the settings portal, precisely those entries that we are able
+to read and match with our own table.
