Description

when creating a new node with topological editing active this happens:

expected behaviour would be being able to create a new node for both adjacent polygons, which works for me most of the time.

I attached a Project file and gpkg.

[vertex tool] Fix vertex addition to polygon's first segment (fixes #20774)

With topo editing mode enabled, addition of extra points to keep the topology
correct wasn't working correctly because for the first segment we were getting
two matches due to duplicated first and last vertex in the ring. The fix
ensures that only one match will be returned for the first duplicated vertex.
