Ok, thanks. I found and corrected a bug in luatex: the last 'single'
glyph in a chained list was always ignored because the fact that it
had extensible tags took precedence over its actual size.

Hans and I never noticed because both Cambria and LatinModern have
single delimiters up to such a large size that the visual difference
becomes negligible.

Best wishes,
