/* Threaded ticket comments
========================
See the #prefs form in ticket.html.
We have three mutually exclusive orders, 'newest' first, 'oldest'
first and 'threaded'. In addition, changes without comments can be
filtered out.
When switching to 'threaded', the changes without comments must be
shown again as they can also have a follow-up. After appending
eventual children, they must be hidden again and `:has(.comment)`
will now take into account the threaded comments in
children. Likewise, when switching away from 'threaded' to a linear
order, the changes without comments need to be hidden again.
