I'll check on those notifiers; I've been trying to keep them in-line with future ZC base values.
To be clear, the highlighted portion does not fully occur. The "product" itself remains, but the attributes associated are removed. Permanently. They can be "added" back in only if the product is added with the associated attributes (costs and other characteristics), but an update from the current page (whether adjusting the attributes or not) plain removes attributes from all product whether the product was edited or not.

Seeing that little has/had changed in the base "direction" to remove and add product's to the order, my search led me to consider other "black boxes" with current review of the admin's attributes class because of the breadth of changes that were made between the current version and a version that I could readily identify as previously working (4.1.7). (I know a long time ago. :) ).
