I don't think the spec is so explicit about ignoring the selection 
attribute or having other requirements on the number of children. 
However, it essentially describes the expected behavior of these known 
action types so I assumes one obviously understands that the specific 
description supersedes the general one (I don't know if it was 
intentional or not but note however that the original developer of the 
Mozilla code considered the selection attribute even with the statusline

Yes, I think that's fine. At least that should allow Andrii to write a 
patch to conform to this behavior.
