Yes, this appears to be the culprit leading to the incorrect values from
'X-extent (and calling ly:grob-extent).

Would you mind trying out the attached patch to see if it works in whatever
context you need AccidentalPlacement info for?

With your example, I get the same values as with 2.16.2, except in the case
of the five-note chord.  The accidentals in later releases are spaced
closer, presumably as a result of skyline work.
