musicxml2ly: direction element (words+dashes) wrongly converted to markup with trillspan

[Gmx via bug-lilypond]

Hi team, 

I would like to report a bug:

I have a musicxml export from Musescore where I have added a crescendo line  
“cresc. _ _ _ _ _ _ “ spanning several notes. 

When converting that musicxml to ly (musicxml2ly 2.24.3)  it will be rendered 
as a trill with span:

PartPOneVoiceOne =  \relative f'' {
    \clef "treble" \time 4/4 \key c \major | % 1
    f4 -\markup{ \small\italic {cresc.} } \startTrillSpan f4 f4 f4
    \stopTrillSpan }

The same error happens with diminuendo line as well (probably with any musicxml 
direction which has words+dashes).

Here is the musicxml:
