[Window] WindowPlacement.Maximized makes undecorated window fullscreen

Bug Description

On an undecorated window, using WindowPlacement.Maximized makes the the window fullscreen, when it should be maximised.

Reproducer

fun main() = auroraApplication {
    AuroraWindow(
        skin = geminiSkin(),
        onCloseRequest = ::exitApplication,
        state = WindowState(placement = WindowPlacement.Maximized),
        undecorated = true
    ) { }
}

Actual Result:

The window becomes fullscreen.

Expected Result:

The window should be maximised (staying above the taskbar).

Platform Info

Aurora Version: Tested on both 1.1.0 & 1.2-SNAPSHOT

Operating System: Windows 11

Indeed:

fun main() = application {
    Window(
        onCloseRequest = ::exitApplication,
        state = WindowState(placement = WindowPlacement.Maximized),
        undecorated = true
    ) { }
}

Shows the same issue - maximized treated as fullscreen

I’m not even sure that I can work around this without causing an extra frame of flicker from fullscreen to maximized mode on initialization. Probably the safest (but a bit cumbersome) is to use the code suggested on that second issue.
