Alright I think I figured it out.

The system is loading the first 10 notifications of all types, but any further loads are done only with the default content types - which apparently (as I have confirmed) include both discussion replies and discussion upvotes, but not at-mentions.

As a result, any notification of a non-default type that happens to be beyond the first ten is never loaded.

Any notification of a deafult type (discussion replies and upvotes) that happens to be beyond the first global ten, but within the first default ten, isn't loaded as well - but those will come back when they reach the next ten (I have confirmed that).

On legacy wikis it works pretty much the same, but since UCP wall notifs are omitted even from the first 10, it may show some notifs that are not visible up on a UCP wiki at the same time (I have confirmed that too).
