here is the one that I would expect to behave the same as the if, but breaks

fun CustomTooltip(
    parentComposable: @Composable () -> Unit,
    tooltipContent: @Composable () -> Unit,
    showTooltip: Boolean,
    popupPositionProvider: CustomPopupPositionProvider,
    modifier: Modifier = Modifier
) {
    Box(modifier) {
        parentComposable()
        AnimatedVisibility(visible = showTooltip) {
            Popup(popupPositionProvider = popupPositionProvider) {
                tooltipContent()
            }
        }
    }
}


here is the original that behaves properly and positions to the correct side of the parent composable

fun CustomTooltip(
    parentComposable: @Composable () -> Unit,
    tooltipContent: @Composable () -> Unit,
    showTooltip: Boolean,
    popupPositionProvider: CustomPopupPositionProvider,
    modifier: Modifier = Modifier
) {
    Box(modifier) {
        parentComposable()
        if (showTooltip) {
            Popup(popupPositionProvider = popupPositionProvider) {
                tooltipContent()
            }
        }
    }
}

var animateVisibility by remember { mutableStateOf(false) }
    val coroutineScope = rememberCoroutineScope()
    coroutineScope.launch {
        delay(500)
        animateVisibility = true
    }
    Box(modifier) {
        parentComposable()
        if (showTooltip) {
            Popup(popupPositionProvider = popupPositionProvider) {
                AnimatedVisibility(
                    visible = animateVisibility,
                    enter = fadeIn(
                        // Fade in with the initial alpha of 0.3f.
                        initialAlpha = 0f,
                        animationSpec = TweenSpec(durationMillis = 2000)
                    )
                ) {
                    tooltipContent()
                }
            }
        }
    }
