TextSpan behaviour

[Ole Schmidt]

Dear all,

I worked out something with a TextSpanner which behaves (as it should  
be) as a snippet:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\version "2.10.15"

\new Staff {

\override Voice.TextSpanner #'padding = #2.5
\override Voice.TextScript #'padding = #2.5
\relative c''
{ \time 2/4 fis8[\< g8](\glissando \override TextSpanner  #'edge-text  
= #(cons (markup #:italic "poco movendo al"  )"") fis8.--) 
\startTextSpan\f\![ g16]\p ~ |

\times 2/3 { g16[ d\< ~ d8 dis8]\mf\! ~ } \times 2/3 { dis16[ fis16\p 
\< ~ fis8\glissando g!8]\! ~ } |
        
g16^\markup {\smaller \general-align #Y #DOWN \note #"4" #1 = 72 } 
\stopTextSpan[ g8--\mf fis16--]\f ~ fis8[ g!8] ~ |

}
}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

In my big score the TextSpanner is a short solid line instead of  
dotted lines  until the markup (see jpg). Which could be the reason?

Thank you for a hint

best
