+Subject: [PATCH 12/33] [meta-browser] Fix "constexpr variable cannot have
+ non-literal type" errors
+
+Something about Chromium's `base::flat_map` /
+`base::internal::flat_tree` isn't considered a literal type by older
+clang versions, meaning they can't be used in constexpr expressions. We
+need to change them to be const instead.
+
+Upstream-Status: Inappropriate [specific to older versions of clang]
