Is there any reason to special case this? Can't you always set it? Additionally
I think you only need the size.

Yes, because in case of a revert I need to know if there was a restore bound or
not. And note that this can be different (but does not have to be) from the
initial_bounds as well.

Additionally: Once I removed the old restore state, I need size and location -
otherwise we cannot perform an abort from the resize.
