MultiSelectListPreference checkboxes not checked when not initially visible in list (API 23)

Question

Given a SettingsActivity with just a MultiSelectListPreference with its entries, values, and default values in array resources, some checkboxes are not drawn as checked even though Android knows they are supposed to be checked. When an unchecked item is clicked, the item remains unchecked (because Android thinks it is unchecking a checked item).

Here's a video of this happening

It seems to work fine in APIs 21 and 22, but not in 23. Is this maybe a bug in the recycling of views? Or what might be the cause?

SettingsActivity.java

package com.immersibleelf.mslpbug;

import android.os.Bundle;
import android.preference.PreferenceFragment;
import android.support.v7.app.AppCompatActivity;

public class SettingsActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Display the fragment as the main content.
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new SettingsFragment())
                .commit();
    }

    @Override
    public void onPause() {
        super.onPause();
    }

    public static class SettingsFragment extends PreferenceFragment {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            // Load the settings from an XML resource
            addPreferencesFromResource(R.xml.settings);
        }
    }
}

A workaround is to create a sub class of MultiSelectListPreference and overwrite the method showDialog like this:

@Override
protected void showDialog(Bundle state) {
    super.showDialog(state);

    AlertDialog dialog = (AlertDialog)getDialog();
    if (dialog == null)
        return;

    if (Build.VERSION.SDK_INT >= 23) {
        ListView listView = dialog.getListView();

        listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                int size = view.getChildCount();
                for (int i=0; i<size; i++) {
                    View v = view.getChildAt(i);
                    if (v instanceof CheckedTextView)
                        ((CheckedTextView)v).refreshDrawableState();
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                int size = view.getChildCount();
                for (int i=0; i<size; i++) {
                    View v = view.getChildAt(i);
                    if (v instanceof CheckedTextView)
                        ((CheckedTextView)v).refreshDrawableState();
                }
            }
        });
    }
}
