In the PR below, we found an issue with wp-each where due to a bug in iAPI the derived lineItemTotal gets out of sync. (see #58370 (review) )

Render cart items in Mini Cart drawer with iAPI, support increase / decrease quantity by samueljseay · Pull Request #58370 · woocommerce/woocommerce

We will need to address this before release. The plan is that we will either:

1. Ship a fix in the WooCommerce iAPI fork
2. Wait for a fix to be shipped in the core iAPI runtime

This issue is to track what we decide to do about this, because at this stage we don't have a good workaround for this bug.
