SwingPanel is always on the top

[MohamedRejeb]

Describe the bug If I use android Views or iOS UIKit interop with Compose the z index is respected and I can have a composable on top of a UIKit View for example but for desktop it's not the case, swing components are always on the top.

Box {
    SwingInterop()
    Text("Demo text") // this text should be visible on top of swing
}

Affected platforms

• Desktop

Versions

• Kotlin version*: 1.9.20-Beta
• Compose Multiplatform version*: 1.5.10-beta01
• OS version(s)* (required for Desktop and iOS issues): macOs
• OS architecture (x86 or arm64): arm64
• JDK (for desktop issues): 17

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

1. Create a Box composable
2. Add SwingPanel
3. Add any other composable under the SwingPanel
4. The composable is not going to be visible

Expected behavior The composable should be on top of the SwingPanel

Additional context In my case I'm using JavaFX WebView, I'm not sure if it's a common problem or related to using JavaFX
