Component gets improperly patched

[sdegueldre]

On branch master-pdis_batch-moda-sad

activate batches for preparation display with custom batches in the settings and create two custom batches

In the pos restaurant, click on a table, start a batch and add a product, start another batch and add another product. The added product never appears despite having been returned by the render function. Add one more product. The component appears in the component tree but not in the DOM, it has status 0 despite being in its parent's children.
