GPX drawer gets confused when traces re-enter bounding box

This always happens when I download the GPS traces of the displayed area and tell JOSM to draw lines between the GPX waypoints. These strange lines always seem to reach from one end of the bounding box to another, usually where streets enter the bounding box. I guess JOSM is having problems when the trace exits the bounding box and re-enters it somewhere different, then it draws a line between those two points. I suppose this problem could be fixed by defining a limit of for example 15 seconds: if more time has passed between to waypoints, then no line is drawed between them.

You can define such a limit (in meters) in JOSM's config. The main problem is the API of OSM, which does not allow to analyse the data properly.
