[NTG-context] Recomputing useMPgraphic in footers

	Hello,

I have

\defineoverlay[Wave][\useMPgraphic{Wave}]

\startuseMPgraphic{Wave}
...
\stopuseMPgraphic

\setupbackgrounds[footer][text][background={Wave}]

The problem is that the graphics is not re-computed on every page,
although I pretty convinced it should.

On the opposite, when I set
\setupbackgrounds[text][text][background={Wave}]
it works perfectly well. (The difference is in [footer] vs. [text].)

An ugly workaround is to call \setupbackgrounds on every page, but it's
not nice at all. What went wrong?

Thanks,
D.A.
