No, it doesn't help! One workaround is described in 
http://lsr.dsi.unimi.it/LSR/Item?id=285, but it
- fails to show what it's supposed to show since you need an additional 
\textLenghtOn in version 2.12 and later
- affects the horizontal spacing

The following modified version works better:

\new Staff {
 \override TextScript #'staff-padding = #4
 \override TextScript #'self-alignment-X = #center
 \textLengthOn
 \time 2/4
 c'4_\markup { \combine \transparent "f" "WRONG" }
 c'4_\markup { "case" }
 c'4_\markup {  \combine \transparent "f" "RIGHT" }
 c'4_\markup {  \combine \transparent "f" "case" }
}


(I will send an update to LSR).

The discussion you cited above does indeed provide the solution, but to 
a slightly different problem, namely the vertical alignment of lyric 
lines, not of text scripts. Also, that solution only applies to the 
latest 2.13 version, not to 2.12.
