Price data on one of configurable_children deleted

[didkan]

When using api-search-query (and hence response_format=compact in the api request querystring), one of the configurable children is missing most of its pricing data.

The code that removes it is this:

vue-storefront-api/src/processor/product.js

Lines 65 to 69 in 1e62369

	fieldsToCompress.forEach(field => {
	if (item._source[field] === subItem[field]) {
	delete subItem[field] // remove fields that are non distinct
	}
	})

We have a customized vsf-default theme that will display price data in the options dropdown on the PDP for configurable products. This breaks that.
I'm not sure if this is a bug or a feature?!
It can easily be "worked around" by removing the fields we want to retain from config.products.fieldsToCompress, but wanted to add an issue to at least shine a light on the "breaking change".
