Comment on attachment 314258 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=314258&action=review > Source/WebCore/platform/graphics/mac/FontCacheMac.mm:86 > + // The special cases in this function need to match the behavior in FontDescriptionCocoa.cpp. On systems where > + // USE_PLATFORM_SYSTEM_FALLBACK_LIST is set to true, this code is used when src:local(special-cased-name) is > + // specified inside an @font-face block, and the code in FontDescriptionCocoa.cpp is used for regular (element > + // style) lookups. > + // FIXME: Currently, an @font-face block corresponds to a single item in the font-family: fallback list, which > + // means that "src:local(system-ui)" can't follow the Core Text cascade list (the way it does for regular lookups). > + // These two behaviors should be unified, which would hopefully allow us to delete this duplicate code. Maybe have this comment in just one place, and in the other say "// FIXME: see comment in ..."
