This is not a huge deal, but would be nice to see fixed - if that is possible. Attached is a small test project with a set of lines taken straight from OpenStreetMap. The ref=* tag for the lines all have the same identical value, in this case 1, and the [x] merge connected lines to avoid duplicate labels is checked. Yet, two labels are created.

Again, nothing urgent, but would be lovely to have this corner case handled properly.

The set of lines in the attached project have two 3-way junctions (see screenshot 13852.png). The function FeaturePart::mergeWithFeaturePart supports only continuous LineString and therefore multiple labels are created
