Preview fails to render when there's a SwingPanel

[asapha]

The preview pane is stuck on "Rendering preview" when trying to preview this

@Preview
@Composable
private fun TestPreview() {
    SwingPanel(
        factory = { JTextArea("Hello world") }
    )
}

@asapha and with plain Compose it works fine on your system?

[asapha]

Yes it works, although I needed to add a size (modifier = Modifier.size(80.dp)) to the call for anything to appear.

Further info: I need to restart the IDE in order to make any other preview work after trying the above.

Reproduced with the same idea, plugin build 310.
