setCloseButtonIcon() method doesn't change default Close button

问题

I try to change default icon for Close Button in Chrome custom tabs (CustomTabsIntent.Builder)

Simple code for testing:

Bitmap closeIcon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
intentBuilder.setCloseButtonIcon(closeIcon);

But nothing happens. Why? (Nexus 7, Marshmallow)

Typically this is caused by using a bitmap that has the 'wrong' dimensions. The correct dimensions are documented here: https://developer.android.com/reference/android/support/customtabs/CustomTabsIntent.html#KEY_ICON
