Slurs not allowed to cross barlines, leading to placement far from notes

I had tried to find a clear statement in Gould about this but failed. Here is the default layout for a particular example from the forum (https://musescore.org/en/comment/reply/node/280131/):

If you turn off autoplace, you get this, which to me is better:

There are going to be any number of cases where our strategy of simply moving a slur up in case of collision is going to yield bad results, but most of those cases would require reshaping the slur while is going to be complicated. This particular case is much simpler though - I will bet we just need to skip barlines when checking for intersections in slurPos. Before actually implementing this, we should verify there isn't a rule against it somewhere, of course.
