set Content View Top Padding
Sets the top padding (in pixels) of the sibling content view that holds overlay views such as the thumbnail grid. After the first call the automatic Java-side adjustments triggered by contextual toolbar lifecycle events are suppressed, so Compose can own this value without racing against native view code.
Typical usage: call from a LaunchedEffect keyed on the collected viewWithOverlappingToolbarShown value (and the measured toolbar height) so the padding stays in sync. Reading those states only inside a SideEffect body does not subscribe the composition to them, so the effect would never re-run when the overlay opens.
