Problem when a long decoration acrosses more than two rows

[thuhuwei]

For example, the 8va line cannot be seen in the 2-nd row. I found the same problem for long !trill(! lines too.

What's wrong?

the abc example:

X:1
Z:?
L:1/4
Q:1/4=145
M:4/4
I:linebreak $
K:C
V:1 treble
V:1
(!8va(!e/d/ e/g/ | !2!d/e/4g/4 e/4d/4!1!c/ !3!A/G/ A/c/ | G) z!mf! (!3!e/d/ e/g/ | $
!2!d/e/4g/4 e/4d/4!1!c/ !3!A/G/ A/c/ | G) z/ z/4!f! (.a/4 .g/.c'/ .a/.g/ |
.e/.a/ g/)!p!(e/ .g/.c'/ .a/.g/ | .e/.a/ g/)!f!(e/ g/4a/4g/4e/4 d/4e/4g/ | $
a/4g/4e/4d/4 c/e/ d/4e/4d/4c/4 A/c/!8va)! |

Ottava is only defined as a single symbol that stretches from !8va(! to line end or !8va)!, whichever comes first, and from line start or !8va(!, whichever comes last, to !8va)!.
It is not handled like a beam, only the notes in between opening and closing tags are shifted by an octave.

Sorry for this bug asks for too much development.
