Tram tracks have gaps right before bridge (layer=1)

[johsin18]

The problem appears for tram tracks crossing a bridge. On the bridge, they are tagged with layer=1, which I assume to be correct. Before the bridge, they have no layer tag set (so it defaults to 0). There is no map element that would match/cover the rendered gap in (i.e. having that position).

Expected behavior

Tram tracks are rendered as a continuous line.

Actual behavior

Tram tracks are rendered as a line with gaps.
