The copying may work if the feature is switched on for all buffers. The=20
reason for this is that things have to be reevaluated/fixed anyway every=20
time some buffer changes (e.g. insertion or deletion of a character)=20
happens. So if the text is copied to a buffer that doesn't do any=20
explicit reordering on top of the bidi algorithm, the special=20
overlays/properties/whatever will just be purged out.

On the other hand, it may also make sense to copy a piece of TeX *with*=20
the explicit TeX-specific reordering, because otherwise it may look like=20
garbage. Please remember that the goal of all these activities is to=20
make TeX or HTML/XML *legible*, because it's often illegible just with=20
the basic bidi algorithm.
