def test_buildCOLR_v0_layer_as_list():
# when COLRv0 layers are encoded as plist in UFO lib, both python tuples and
# lists are encoded as plist array elements; but the latter are always decoded
# as python lists, thus after roundtripping a plist tuples become lists.
# Before FontTools 4.17.0 we were treating tuples and lists as equivalent;
# with 4.17.0, a paint of type list is used to identify a PaintColrLayers.
# This broke backward compatibility as ufo2ft is simply passing through the
# color layers as read from the UFO lib plist, and as such the latter use lists
# instead of tuples for COLRv0 layers (layerGlyph, paletteIndex) combo.
# We restore backward compat by accepting either tuples or lists (of length 2
# and only containing a str and an int) as individual top-level layers.
