Hi,
thank you for reporting this bug (and for the useful details !)

First the reason why desklets are normal windows is to allow for usual
window placement by dragging it (activated by gtk_window_begin_move_drag,
which allows the WM to place it, including visual effects like "wobbling
window" for Compiz). Dock windows can't be moved like that (nor desktop
windows).
It also allows the desklet to be placed like normal windows, if ever the
user wants it.

Now, I think we can work around the first point, and the 2nd point is
probably useless (most probably, the user wants its desklets to be either
always above or always below).
So I think your point is valid, making them Dock windows is the solution (a
Desktop window wouldn't work because the main desktop window goes over it
when clicking on the desktop, making it invisible, at least I noticed that
on XFCE).

Meanwhile, please consider using the "Show-desktop" applet, which has 2
modes, one to hide every windows, another to hide windows except desklets
:-)

>   Reproduction Steps:
>   1/ openbox with cairo dock. Have the clock plug-in detached and shown on
> the desktop;
>   2/ have some normal windows opened;
>   3/ Show the desktop using openbox ToggleShowDesktop action; => the
> windows hide, as expected
>   4/ Try to "unshow" the desktop by repeating the ToggleShowDesktop action.
>
>   Expected result: the previously hidden window should unhide so that you
> get back to state of the desktop in step 2/.
>   Actual Result: all windows stay hidden.
