There are a lot of macros in our code that tree-sitter based C mode gets right, so I'm not sure this is accurate. > So my guess is that this is going to be a "wont fix". Maybe we should grow some augmentations for tree-sitter, at least given enough time. Or maybe it's possible to identify the parts where this happens by some tree-sitter indications, and tweak the faces in those regions in some way.
