Ole Rehmsen a970d4e834 Imperative named Slots
The idea is to instead of imperatively appending slotted comments to
threadGroupEls (which results in them being removed from the light DOM
of the gr-diff element and thus causing all kinds of tracking
difficulties), to slot them into a named slot in the appropriate line.
