Trip headers spanning more than one line where broken at incorrect
locations in the string. Not exactly sure, but I think this came with
the newest Kirigami SHA, and especially the Label change.
Carefully reading the code for the trip heading shows a "strange"
negative margin. So the margin is on the outside. This margin was
used to split the string, allowing for a small invisible part of
the string to present as trip header.
This is solved by this commit.
