I'm tempted to think that it *is* a VirtualBox issue: in fullscreen mode it tries to behave as much as possible as if you're not working on a VM guest. It doesn't surprise me that it tries to catch power-related events too. I'd suggest you ask on Oracle's VirtualBox forum if there's a way around (like a setting to let the host handle these events) and if not, file a ticket with a request.

Can you just tell VirtualBox to drop out of fullscreen mode and then let the host continue processing as usual?

Personally I usually do this manually and then pause the guest before I suspend the host. Enough happens on wake-from-suspend that things usually go smoother if there isn't also a VM guest (which typically has a huge memory footprint) that tries to do those same things at the same time.
