problem with \with-dimensions

[Werner LEMBERG]

[git 1b5411df from today]


This snippet

  \relative c'' {
    c1
  \override Score.RehearsalMark.break-visibility = #end-of-line-visible
  \override Score.RehearsalMark.extra-offset = #'(0 . -.25)
    \mark \markup {
      \with-dimensions #'(0 . 0) #'(0 . 0) {
        \column {
          \musicglyph #"scripts.ufermata"
          \vspace #1
          \musicglyph #"scripts.dfermata"
        }
      }  
    } \bar "|."
  }

no longer works as expected, see image.  At least with 2.17.0, I get
the fermatas correctly positioned (using old syntax, of course).  Has
something changed?  Is this a bug?
