Showkase browser doesn't work with empty @Preview BackHandler

[ReginFell]

If you have BackHandler which does nothing inside @Preview it breaks navigation for Showkase browser

Snippet to reproduce:

@Composable
fun ContentScreen(
    viewModel: ContentViewModel = androidx.lifecycle.viewmodel.compose.viewModel(),
) {
    Content(onBack = viewModel::onBack)
}

@Composable
fun Content(onBack: () -> Unit) {
    BackHandler(onBack = onBack)
}

@Preview
@Composable
fun ContentPreview() {
    Content(
        onBack = {},
    )
}

If you open ContentPreview from Showkase browser, it will not be possible to navigate back

One potential fix could be making LocalInspectionMode.current return true for Showkase scope, this way we can either add or not add backpress handler based on LocalInspectionMode

@ReginFell I was able to repro and have a fix pushed for it
