style.fontFamily does nothing

Summary: Although looking at the code shows support for fontFamily, I cannot make it work.

To reproduce:

@Preview
@Composable
fun DebugMarkDown() {
    Column(modifier = Modifier.background(Color.Blue)) {
        val style = TextStyle(fontFamily = FontFamily.Cursive, color = Color.White)
        val s = "Test"
        Text(text = s,
            style = style)
        MarkdownText(
            markdown = s,
            style = style
        )
    }
}

which previews as:

Expectation: Text would be rendered identically for both Text() and MarkdownText()

Actual: Text() renders using fontFamily, but MarkdownText ignores it.

I wasn't using the latest version which DOES have fontFamily support.
