TextField/BasicTextField not adding new line on NumPadEnter.

[antontucek]

Describe the bug
When using TextField/BasicTextField with singleLine = false, I would expect to add new line on NumPadEnter press, but it doesn't. The behavior is different from when pressing normal enter or Swing JTextArea in general.

Affected platforms

• Desktop

Versions

• Kotlin version*: 1.9.20
• Compose Multiplatform version*: 1.5.11 (also tried on 1.6.0-alpha01, the bug persists)
• OS version: Windows 11
• OS architecture: x86
• JDK (for desktop issues): 17

To Reproduce

1. Run

fun main() = application {
    Window(onCloseRequest = ::exitApplication) {
        Column {
            Row {
                var textState by remember { mutableStateOf("") }
                TextField(
                    value = textState,
                    onValueChange = { textState = it },
                    modifier = Modifier
                        .padding(start = 4.dp, end = 4.dp)
                        .fillMaxSize(),
                    singleLine = false,
                )
            }
        }
    }
}

2. Click into TextField.
3. Press NumPadEnter
4. See that no new line added.

Expected behavior
A new line added.
