this also fixes the connecting lines in the Sk-style view
thanks @ShittyKopper for reporting the bug!
NOTE: at this point, the `isDeletedRef` boolean is pretty much
useless, because we're directly removing deleted notes from the
`replies` array and therefore from the DOM (we were just hiding them,
before); I'm intentionally not touching `isDeletedRef` to simplify
merges from upstream
`useNoteCapture` already subscribes to all updates for a note, so
we can tell it when a note gets replied to, too
Since I'm not actually adding any extra subscription in the client,
just an extra callback, there should be no overhead when replies are
not coming in.
Also, all the timelines already call `useNoteCapture` for each note
displayed, so we know the whole `GlobalEventService` thing works fine.
Many thanks to VueJS for taking care of all the DOM complications
