Well, the above given example can be fixed by moving
Mark_tracking_translator as well.
Though, this is not well documented, imho, the entry in `changes' is
hard to understand without code-example.
Nothing in NR.
The regtest input/regression/mark-tracking-context.ly is nice and
matching above use case, but users are not expected to look there.
