如何实现三条或多条 b3-menu__separator 之间的按钮全是 display:none 就把 b3-menu__separator 处理到只剩一条？目前只实现了两条

            if (_seperateHidingPolicy_ == 3) {
                // test seperate and hide if two meet each other
                // TODO: didn't handle the situation that more than two seperators meet each other....
                // 烧脑。。。
                let startSeparatorIndex = -1;
                let previousSeparatorHidden = false;
                for (let i = 0; i < _items_.length; i++) {
                    if (_items_[i].classList.contains('b3-menu__separator')) {
                        if (startSeparatorIndex === -1) {
                            startSeparatorIndex = i;
                        } else {
                            let allButtonsHidden = true;
                            for (let j = startSeparatorIndex + 1; j < i; j++) {
                                if (_items_[j].style.display !== 'none') {
                                    allButtonsHidden = false;
                                    break;
                                }
                            }
                            if (allButtonsHidden && !previousSeparatorHidden) {
                                _items_[startSeparatorIndex].style.display = 'none';
                                previousSeparatorHidden = true;
                            } else {
                                previousSeparatorHidden = false;
                            }
                            startSeparatorIndex = i;
                        }
                    }
                }
            }
