Window size isn't preserved when we change the system density

Compose 1.0.0-beta5, Windows 11, OpenJDK 15

import androidx.compose.ui.unit.dp
import androidx.compose.ui.window.WindowState
import androidx.compose.ui.window.singleWindowApplication

fun main() = singleWindowApplication(
    state = WindowState(width = 500.dp, height = 500.dp)
) {
}

Pure Swing reproducer:

import kotlinx.coroutines.DelicateCoroutinesApi
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.GlobalScope
import kotlinx.coroutines.delay
import kotlinx.coroutines.launch
import kotlinx.coroutines.swing.Swing
import java.awt.Dimension
import javax.swing.JFrame

@OptIn(DelicateCoroutinesApi::class)
fun main() {
    val frame = JFrame()
    frame.size = Dimension(500, 500)
    frame.isVisible = true

    GlobalScope.launch(Dispatchers.Swing) {
        while(true) {
            delay(1000)
            println(frame.size)
        }
    }
}

If we just move the window between two displays with different densities - everything is fine.
