|
* The apps used to label order rows by downloading the ENTIRE catalogue and

|
|
* joining it in the browser (composables/useOrderItemProduct.ts). With the real
|

|
|
* catalogue at ~16k products that is the wrong trade for a few row labels, and

|
|
* it was also broken for the case order history exists for: a product that has
|
||
|
|
* since left the storefront is absent from the catalogue, so the row rendered
|
||
|
|
* blank.
|
||
|
|
*
|
||
|
|
* Both apps now read these fields straight off the item, so the include is part
|
||
|
|
* of the contract — hence a test, which this method did not have.
