I have an ElevatedCard in my app and it looks really good:

and its code is here:

ElevatedCard(
    content = {
        Text(
            fontSize = 20.sp,
            text = "All cars",
            modifier = Modifier.fillMaxWidth().padding(horizontal = 10.dp, vertical = 12.dp)
        )
    },
    onClick = {

    },
    modifier = Modifier.padding(horizontal = 8.dp, vertical = 4.dp)
)

However, when I add more composables/views, an icon button and a text, there appear unexpected shadows at the corners while the shadow on sides and up and below almost disappear (I don’t know how to describe it better):

and when it gets expanded:

Here is the code:

var expanded by rememberSaveable { mutableStateOf(false) }

ElevatedCard(
    content = {
        Row(
            content = {
                Text(
                    fontSize = 20.sp,
                    text = "All cars",
                    modifier = Modifier.weight(weight = 1f).padding(start = 6.dp)
                )

                IconButton(
                    onClick = {
                        expanded = !expanded
                    },
                    checked = expanded,
                    icon = R.drawable.ic_chevron,
                    contentDescription = R.string.expand,
                    tint = MaterialTheme.colorScheme.secondary
                )
            },
            modifier = Modifier.padding(horizontal = 4.dp),
            verticalAlignment = Alignment.CenterVertically
        )

        ScaleVisible(
            content = {
                Text(
                    fontSize = 14.sp,
                    color = Color.DarkGray,
                    text = "All cars from the latest catalog.",
                    modifier = Modifier.padding(bottom = 4.dp)
                )
            },
            visible = expanded,
            modifier = Modifier.padding(horizontal = 10.dp)
        )
    },
    onClick = {
        expanded = !expanded
    },
    modifier = Modifier.padding(horizontal = 8.dp, vertical = 4.dp).animateContentSize()
)

As you can see there changes something and makes the ElevatedCard work incorrectly.

I also played a lot with paddings around the card and within its content, but no changes.

What I do wrong?
