This behaviour is caused by the settings for markLengthOn, the default:

markLengthOn = {
  \override Score.MetronomeMark.extra-spacing-width = #'(0 . 1.0)
  \override Score.RehearsalMark.extra-spacing-width = #'(-0.5 . 0.5)
  % Raise as much as four staff-spaces before pushing notecolumns right
  \override Score.MetronomeMark.extra-spacing-height = #'(4 . 4)
  \override Score.RehearsalMark.extra-spacing-height = #'(4 . 4)
}

Chord-names like Cis consum more horzontal space than C.
A fermata will push a chode-name above, thus more vertical space.

If you change the values '(4 . 4) to '(1 . 1) it's consistent. At
least with my testings.
