A solution I use is with the New Symbology, I create two lines for the polygon (Outline: Simple Line). The first line on top is the dashed line. The second line below is white solid line or any background color with the same thickness or larger than the dashed line on top (similar to a halo/buffer effect on texts). The white will cover the first overlapping polygon and will only show the polygon on top.
