Continuing from closed bug 616724, the behavior of the Previous/Next buttons in the separated message window (double-click on a message) is not consistent with the same buttons in the main window of Evolution.

In the main window the Previous/Next buttons respectively move up and down in the message list no matter its order.

In the message window they always go respectively to the older/newer message in chronological order.

This differs from evolution pre-2.30 behavior and is inconsistent: for example, if you order the messages by date with the most recent message on top the Next/Previous buttons in the main window go respectively to the newer/older message, but in the separated window they go respectively to the older/newer message. If the message list in the main window is ordered by author, or subject there's now way to predict what message will be selected.

The separated mail window's message list should inherit all the properties of the main window's message list.

I didn't use a release of evolution including the patch committed when closing bug 616724, but both the code and the description make me doubt that it addresses this bug as well. In case it does, sorry for the noise.
