Field does not return serialized values via `getSerializedFieldValues()`

[chrismlusk]

When calling the Element's getSerializedFieldValues() method on an element that has a Colour Swatches field in the field layout, the return is not serialized — it's the model.

In the following example, I have an element with a field handle colorTheme.

When I call:

$element->getSerializedFieldValues();

I get:

[
    // other fields, which are all serialized as expected...
    'colorTheme' => percipiolondon\colourswatches\models\ColourSwatches {...}
]

That method calls each field's serializeValues() method here in Craft source.

I do see in this plugin's source that the Colour Swatches field has its own serializeValues() implementation, so I'm not quite sure what is happening.
