HumhubをSafariで使ったときの漢字確定のバグを解消する

HumhubをSafariで使うと、日本語入力でEnterキーを押すと必ず改行になる。これを解消するためにkeyCode = 229のチェックを追加した。

        function inOrNearComposition(view, event) {
          if (view.composing) { return true }
          // See https://www.stum.de/2016/06/24/handling-ime-events-in-javascript/.
          // On Japanese input method editors (IMEs), the Enter key is used to confirm character
          // selection. On Safari, when Enter is pressed, compositionend and keydown events are
          // emitted. The keydown event triggers newline insertion, which we don't want.
          // This method returns true if the keydown event should be ignored.
          // We only ignore it once, as pressing Enter a second time *should* insert a newline.
          // Furthermore, the keydown event timestamp must be close to the compositionEndedAt timestamp.
          // This guards against the case where compositionend is triggered without the keyboard
          // (e.g. character confirmation may be done with the mouse), and keydown is triggered
          // afterwards- we wouldn't want to ignore the keydown event in this case.
          if (result.safari && Math.abs(event.timeStamp - view.compositionEndedAt) < 500) {
            view.compositionEndedAt = -2e8;
            return true
          }
	    if (event.keyCode===229) { return true} #←これを追加する
          return false
        }
