Summary
Clicking a link should preconnect to destination as first party

Clicking a link should preconnect to destination as first party, not third-party. Otherwise, the preconnect is wasted when session isolation based on registrable domain is enabled.

Does this make it so that script can use a.click() to preconnect in the context of another page?

I assume this makes it so that we don't preconnect for a link that is supposed to open in an iframe, right?

I think it does. But since this will cause a top-level navigation, we would anyway connect to that server as first party, no?

Yes, since we are now preconnecting as first party and since we want session partitioning, it only makes sense to preconnect if clicking the link is going to cause a top frame navigation.
