Initially expanded BottomSheetDialog not working

I have the following bottom sheet dialog code:

abstract class BaseMvpBottomSheetFragment : BottomSheetDialogFragment() {

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val dialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog

        if (isFullscreen) { // true
            dialog.setOnShowListener {
                val bottomSheetDialog = it as BottomSheetDialog
                bottomSheetDialog
                    .findViewById<FrameLayout>(com.google.android.material.R.id.design_bottom_sheet)
                    ?.let { bottomSheetFl ->
                        from(bottomSheetFl).apply {
                            state = STATE_EXPANDED // This code is called, I've checked it with debugger
                        }
                    }
            }
        }

        return dialog
    }

And the following layout:

<?xml version="1.0" encoding="utf-8"?>

            <androidx.appcompat.widget.AppCompatEditText

                android:maxLines="1"
                app:layout_constraintTop_toBottomOf="@id/closeIv" />

        </androidx.constraintlayout.widget.ConstraintLayout>

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/modelsRv"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintTop_toBottomOf="@id/headerLayout"
            tools:listitem="@layout/view_item_model" />

    </androidx.constraintlayout.widget.ConstraintLayout>

</FrameLayout>

I want dialog to be initially expanded (and layout to take all vertical space), but when RecyclerView is empty, it takes no space at all:

I've tried other solutions on SO, but they did not work for me.
