The normal solution is to move the parts around so you can get them together with a "blob" rather than a trace.
The issue isn't so much burned traces in normal operation. It's the traces popping off the board when you have some sort of overload situation. With the PTC fuses, a minor fault ( say 20 to 40 A on the 11A fuse) often resists in a max current / no current / max current situation that can go on for a long time (weeks ....).
