BottomAppBar height gets bigger when using window.setDecorFitsSystemWindows(false) - height

Question

I am trying to achieve transparent status bar by using window.setDecorFitsSystemWindows(false) and statusBarColor = Color.TRANSPARENT. I achieved my goal, but when I introduced BottomAppBar, its size (padding to be exact) is doubled. What might be the issue?
With window.setDecorFitsSystemWindows(false):
Without window.setDecorFitsSystemWindows(false):

Got to the answer quickly than I thought I would. I forgot to calculate the insets, so adding this piece of code made everything working again:
ViewCompat.setOnApplyWindowInsetsListener(window.decorView) { view, windowInsets ->
val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())
view.updatePadding(bottom = insets.bottom)
WindowInsetsCompat.CONSUMED
}
