• OS architecture (x86 or arm64): X86

To Reproduce

1. Compile and run the following code:

   import androidx.compose.foundation.layout.Column
   import androidx.compose.material.Text
   import androidx.compose.runtime.*
   import androidx.compose.ui.window.AwtWindow
   import androidx.compose.ui.window.MenuBar
   import androidx.compose.ui.window.singleWindowApplication
   import java.awt.FileDialog
   import java.awt.Frame
   import java.nio.file.Path
   import kotlin.io.path.Path
   import kotlin.io.path.absolutePathString
   
   @Composable
   fun FileLoadDialog(
       title: String,
       visible: Boolean = true,
       onResult: (result: Path?) -> Unit,
   ) {
       AwtWindow(
           visible = visible,
           create = {
               object : FileDialog(null as Frame?, title, LOAD) {
                   override fun setVisible(value: Boolean) {
                       super.setVisible(value)
                       if (value) onResult(file?.let { Path(directory, file) })
                   }
               }
           },
           dispose = FileDialog::dispose
       )
   }
   
   fun main() = singleWindowApplication {
       var load: Boolean by remember { mutableStateOf(false) }
       var path: Path? by remember { mutableStateOf(null) }
   
       FileLoadDialog(
           title = "Load a file",
           visible = load,
           onResult = {
               path = it
               load = false
           }
       )
   
       MenuBar {
           Menu("File") {
               Item("Load") { load = true }
           }
           Menu("Edit") {
               Item("Hello World!") {}
           }
       }
   
       Column {
           Text(if (load) "Loading..." else "Use File > Load to load a file")
           path?.let { Text(it.absolutePathString()) }
       }
   }

2. In the screen's top menu, select "File" > "Load"
3. Select any file and click "Open" (or click "Cancel")
4. See that the top menu (that should show "File" & "Edit") has disappeared.

Note that if the application window loses focus, when the app regains focus, the menu is shown again.
