This problem is fixed for now. At least for me, it works.

PS If it doesn't work for you, ensure you've changed the text value in the onValueChange callback in your @Preview composite! Like this:

@Preview(showBackground = true)
@Composable
private fun InputPrev() {
    var textValue by remember { mutableStateOf("Text") }
    MainTextInputField(
        text = textValue,
        onValueChange = {
            textValue = it
        }
    )
}
