iOS 17 hidden trackpad doesn't work in the TextFields (hold space bar and swipe to move cursor)

[OSemenovBoyarka]

Describe the bug
The iOS 17 introduced hidden trackpad feature, when you can hold the spacebar and then move the cursor with the swipe on the keyboard.
This doesn't move the cursor in any TextField in Jetpack Compose Multiplatform.
Surprisingly - the same feature works fine on Android with the same code.

Affected platforms

• iOS

Versions

• Kotlin version*: 1.9.23
• Compose Multiplatform version*: 1.6.1
• OS version(s)* (required for Desktop and iOS issues): 17.2
• OS architecture (x86 or arm64): arm64
• Device (model or simulator for iOS issues): any iOS device or simulator

To Reproduce
Steps and/or the code snippet to reproduce the behavior:

1. Add a simple text field to the multiplatform app:

@Composable
fun App() {
    MaterialTheme {
        var text by remember { mutableStateOf("") }
        TextField(
            modifier = Modifier.fillMaxWidth(),
            value = text,
            onValueChange = { text = it }
        )
    }
}

2. Run the app on either iOS 17 device or iOS 17 simulator
3. Enter something in the text field
4. Hold the space bar on the soft keyboard and move finger while holding it

Expected behavior
Cursor should move in the direction finger moves. Actually - cursor stays in place.
