Android 同样的参数值下，为什么requiredSizeIn不等于requiredWidthIn + requiredHeightIn

我有以下代码

    LazyColumn(
        contentPadding = PaddingValues(all = 64.dp),
        verticalArrangement = Arrangement.spacedBy(16.dp),
    ) {
        item {
            Box(
                modifier = Modifier
                    .width(200.dp)
                    .height(200.dp)
                    .border(BorderStroke(2.dp, Color.Green))
            ) {
                Box(modifier = Modifier
                    .fillMaxSize()
                    .sizeIn(100.dp, 200.dp)
                    .requiredWidthIn(150.dp, 180.dp)
                    .requiredHeightIn(150.dp, 180.dp)
                    .border(BorderStroke(3.dp, Color.Red))
                )
            }
        }
    }

结果不出所料.

我刚刚用requiredSizeIn替换了requiredWidthIn和requiredHeigthIn，如下所示.

    LazyColumn(
        contentPadding = PaddingValues(all = 64.dp),
        verticalArrangement = Arrangement.spacedBy(16.dp),
    ) {
        item {
            Box(
                modifier = Modifier
                    .width(200.dp)
                    .height(200.dp)
                    .border(BorderStroke(2.dp, Color.Green))
            ) {
                Box(modifier = Modifier
                    .fillMaxSize()
                    .sizeIn(100.dp, 200.dp)
                    .requiredSizeIn(150.dp, 180.dp)
                    .border(BorderStroke(3.dp, Color.Red))
                )
            }
        }

我希望结果是一样的.不知何故，它在高度方面看起来不同.这是为什么？
