Avoid having comments partial load twise. (#4893)

Comments partial had `hx-trigger="load, intersect once"`. This PR
removes `, intersect once`.

Looks like `, intersect once` was a leftover that we missed to remove at
some point. It causes the comment partial to load twice on each page
load for no reason.
