重现步骤
The Modal has a padding-bottom: 24px style, when I set centered props which makes it noticeably uncentered in a scene with a lot of contents.
弹窗上有一个默认属性padding-bottom: 24px，当我设置centered之后，在内容较多的场景下明显不居中
期望的结果是什么？
Completely centered
实际的结果是什么？
noticeably uncentered，unnecessary padding-bottom: 24px at the bottom
