#5522 magnifyStaff breaks noteHead offset in some chords with a 2nd in them and ledger line(s)

[Simon Albrecht]

Reported by Dominic Irving.

If

• a staff is magnified by exactly -0.5
• a chord contains the interval of a second, so one notehead of two needs to be offset
• of those two noteheads, exactly one needs a ledger line
• the chord contains any number of other notes (that are not also clustering against the two mentioned notes)
• and the stem points ‘outward’

the necessary offset of one notehead doesn’t take place.

\version "2.19.83"
\new Staff \with {
  \magnifyStaff #(magstep -0.5)
} \fixed c' {
  \stemDown
  <f d c>4
  <f' d c>
  <f' d' b g d c>
  \stemUp
  <a g e>
  <a' g' e'>
  <c'' b' c>
  <c'' a' g' c>
  <c'' a' g' e' d'>
}

This is fixed in current master and therefore it’s a duplicate of a fixed issue which I’m pretty sure exists but cannot find …
