bug? \lyricsto aligns with markup, not with note

[Arjen Bax]

Hello lily-lovers,

Before filing this as a bug, I thought to ask it on the lilypond users
list first whether is is a bug or a feature.

Using lilypond 2.8.7 (which is the current version on Debian Etch).

When attaching Lyrics to a Voice with \lyricsto and the Lyrics context
is above the Voice context and the note in the Voice context has a
markup attached (with ^ or _), then the Lyrics text will be aligned with
the center of the markup text instead of the note. See example.

When the markup is removed, the Lyrics will be aligned ok.
Also, when the Lyrics context is moved below the Voice context, the
Lyrics will be aligned ok.

Is this a bug? Is there a workaround?

Thank you,
Arjen Bax

\version "2.8.7"

bas = \relative c'' { c1_"This is a rather long markup" }

versII = \lyricmode { Word }

\score {
  <<
    \new Lyrics = basL { s4 }
    \new Voice = basV { \bas }

    \context Lyrics = basL \lyricsto basV \versII
  >>
}
