[BUG] WebView throwing error on configuration

[StefanOltmann]

Hi,

I encountered this Exception while trying to set properties to the WebView:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Not on FX application thread; currentThread = AWT-EventQueue-0
	at javafx.graphics/com.sun.javafx.tk.Toolkit.checkFxUserThread(Toolkit.java:294)

	at com.mohamedrejeb.calf.ui.web.WebView_desktopKt.applySettings(WebView.desktop.kt:173)

We use the WebView like this in commonMain code:

val webViewState = rememberWebViewState(url)

LaunchedEffect(Unit) {

    webViewState.settings.javaScriptEnabled = true
    webViewState.settings.androidSettings.supportZoom = true
}

WebView(
    state = webViewState,
    modifier = Modifier.fillMaxSize()
)

What is the correct way to configure the WebView?

I assume that Platform.runLater() needs to be used, but I can't to that from commonMain.

What can I do to avoid this issue?

@MohamedRejeb Would you consider the Desktop WebView as production ready or is it more experimental state?

Sometimes I get some other weird errors, too.

Are settings only to be applied in LaunchedEffect(state.isLoading)?

Can there be a way to inject settings right in rememberWebViewState() to avoid these issues?
