border - css 曲线边框渲染奇怪

Question

我正在尝试使用 DIV 和 CSS 绘制一些逻辑门。我得到的东西看起来大多没问题，但或中间门 (OR) 在 Chrome 中绘制边框的方式有些奇怪。曲线中有 2 个间隙。同样在所有浏览器中，我检查了或门的左凹曲线在末端变薄。

边框的宽度好像有问题。如果您修改为 1px(每边的 border-top 和 border-bottom)，它在 Chrome 中看起来不错。 Check it out

.gate .orTopRight {
    position: absolute;
    top: 0%;
    right: 0px;
    height: 50%;
    width: 75%;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    background-color: white;
    border-top: 1px solid black; // Modified to 1px
    border-bottom: 0px solid black;
    border-left: 0px solid black;
    border-right: 2px solid black;
    border-radius: 0% 100% 0% 0%;
}
.gate .orBottomRight {
    position: absolute;
    top: 50%;
    right: 0px;
    height: 50%;
    width: 75%;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    background-color: white;
    border-top: 0px solid black;
    border-bottom: 1px solid black; // Modified to 1px
    border-left: 0px solid black;
    border-right: 2px solid black;
    border-radius: 0% 0% 100% 0%;
