Maybe we should simply document that it's valid&expected for the inner
mode to add text-properties to the string.

This looks fiddly, and at least requires changing the doc of
PREVIOUS-CHUNKS to mention that it can contain yet some other data in
some "internal" format.

I can't imagine it being significantly more complex than the string case.
In the worst case, you can fairly easily turn the function into a string
by extracting&concatenating the corresponding chunks.
