Merge branch 'threaded_replies_nightly' into 'nightly'

Fix threaded replies floating

Following Marcus fixes for neo-quitter, I think the floating of replies should be fixed directly in the base theme. What do you think? This issue affects all derived themes (although sometimes only marginally) see https://gnusocial.no/conversation/126588.

These commits implement some of Marcus floating fixes directly in base plus the fav, reply icons are better aligned with the permalink and timestamp (notice-options change).
