Dotted line at end of first segment of continued line goes to bad location if endpoint is on different page

Ubuntu Studio 14.04, GIT commit: 32fe6c4

1) new score
2) text line from measure 1-3
3) add page breaks to bars 1 & 2 (so line continue from page 1 to page 3
4) double click line segment on page 1

Result: the dotted line showing the attachment point for the end handle goes to a seemingly random spot on page. It's actually the coordinates of the line end on page 3, but those coordinates are applied to page 1 instead.

If you do the same with the line segment on page 2, the dotted line goes straight down to the barline. That seems a more sensible solution for page 1 too.

If you make these line breaks instead of page breaks, then you can see the dotted line going to the end of the line at the beginning of the third system, which at least looks more reaosnable, but it's really not. Nothing about editing that first segment will actually affect the end point of the line itself. That is, shift+left/right won't change the anchor. You have actually double click the last line segment to change the end anchor.
