There's nothing to fix; disallowing clients from obscuring or drawing on top of the windows of other clients is an intentional security feature of Wayland, which -- like many security features in general -- makes other things difficult. Sure, we could design a new Wayland protocol for embedding that only we use (and only support it in xfwm4-as-wayland-compositor), but that seems like a poor choice. (At any rate, the idea for this protocol has already been proposed, discussed, and rejected upstream. I don't care to maintain something like this myself.)
As Olivier pointed out, there is already a "blessed" way to do this: an embedded/nested Wayland compositor. I've already started working on one, mainly for the panel's use, but it could also be used here. Unfortunately, this work is a bit more involved than implementing something like the X11-only XEMBED protocol. I have something about 80% working, but am struggling to fix a few remaining issues.
Wayland, as I am learning, is full of trade offs. Some of them I don't entirely agree with, but that's life.
