WHATWG/W3C 動向

Other

  • TPAC topics -- please contribute to this list
  • [css-values-4][css-writing-modes-4] Revisit decision to use 永 instead of 水 as the ic unit
    • https://github.com/w3c/csswg-drafts/issues/7577
    • ic が参照する文字を "水" から "永" に変えようという運動
      • Chrome の intent を見て違和感を持った中国の開発者が SNS で盛り上がった
      • 永字八法(運筆すべてが "永" に入っていること)に馴染み深いこと、タイポグラフィでも基本の文字になっていることから
    • "水" は Writing Modes の縦中横の大きさを決める文字としても使われており、変更すると breaking change になる
      • Level 3 は勧告もしているので、変更にはプロセス的にも負荷のある作業
    • Chromium では仕様の変更には賛成するが、"水" と "永" で幅が変わることはないことから、内部的な実装は "水" のままにするらしい
    • 仕様と実装がばらけるのでそれは避けたいという話になっている
  • [selectors] The forgiving nature of :has breaks jQuery when used with a complex :has selector
    • https://github.com/w3c/csswg-drafts/issues/7676
    • Chrome 105 で :has() が有効になったところ、 jQuery が壊れた
    • jQuery は昔から :has() セレクタや、:contains などを独自拡張として持っていた
      • $() のセレクタはまずブラウザ querySelectorAll() に渡され、 fail したら jQuery のエンジンに渡すようになっている
      • ul:has(li:contains('Item')) といったセレクタはこれまで jQuery で処理されるようになっていた
    • ネイティブ :has() の引数は forgiving selector list をとり、中のセレクタに invalid なものがあっても fail しない
      • なので jQuery 内の :has() がネイティブ実装を参照し続け、 jQuery のエンジンにフォールバックしなくなってしまった
