fix height issue when maxHeight changes while expanded

[phcannesson]

This PR aims to fix the issue mentioned in issue #100, which I'm also facing in my app.

The logic is to update height when maxHeight changes while the toolbar is fully expanded.

Looks like this PR fixes my issue as well because my toolbar uses dynamic height when calculating statusBarHeight. I hope this gets merged asap!

    @Composable
    fun rememberStatusBarHeightDp(): Dp {
        val view = LocalView.current
        val density = LocalDensity.current

        val statusBarHeightPx = remember {
            ViewCompat.getRootWindowInsets(view)
                ?.getInsets(WindowInsetsCompat.Type.statusBars())
                ?.top ?: 0
        }

        return with(density) { statusBarHeightPx.toDp() }
    }

Use this code for top padding
