Damn. I reproduced this immediately. It seems to be an ugly bug. To get around it, go to Mail / Preferences / View and click "classic layout." This will make the panes horizontal, with a dimple on the bottom bar. Grab the bottom dimple and drag up to open up the message pane again. Warning: it may not work the first time. I had to tickle it something like five times and pause at the end of each gesture before it finally responded (and I did the whole experiment twice). When you get the pane back, switch back out of classic mode and it should still be there.
