Section headers of for instance Wikipedia.org pages disappear in reader view. Is this by design or a bug_1) open a wikipedia.org article that has one or more section headers2) swiitch to reader viewThe headers disappear

Currently when I select a closed thread and hit delete the messages are deleted but the close thread header stays the same. It would be awesome if the header text would change to the next thread title!    

When deleting a collapsed group it does not disappear from the list, stays selected but the next collapsed group is actually selected.I almost deleted the wrong group as the user interface is not reflecting correctly what happens. Is this a known bug...
