With conversation view off, marking a message unread from the list --
the hover button, the right-click menu -- marked that message. Opening
it and pressing Mark as unread in the toolbar above it marked every
message in its thread, and so did Move to, Report spam and Delete.
The setting already reaches all the way into the reading pane: the list
draws one row per message, and `visibleMessages` narrows the pane to the
one opened. The toolbar was half converted. Its labels were right --
Mark as unread against Mark as read, the star, the labels shown -- all
of those read `messages`, which is the narrowed set. Only `rowIds`, the
one thing actually handed to the action, still read `thread.emailIds`.
So the button said one message and did the whole conversation.
`rowIds` is now the same question `visibleMessages` answers for the
pane, asked of the same ids, with the same fallback: an id that names
nothing in the thread -- a link from somebody with conversation view on,
a stale `m` in the URL -- shows the conversation, so the toolbar takes
the conversation. Conversation view on is unchanged: nothing is singled
out, so the whole thread comes back as before.
No new strings.
