Adding a node within snap-distance to two ways will connect unconnected ways

[Romwriter]

What steps will reproduce the problem?

1. Select "draw" mode (key "A")
2. Click on a way to add a node

What is the expected result?

The node should be created and inserted into the way. Position of the node should be exactly on the way, so that the segment of the way is kept straight.

What happens instead?

When there is a second (third, ...) way nearby (within snap-distance):

The node is created and inserted into the way AND into all other ways nearby, glueing them together and deforming previously straight ways.

Please provide any additional information below. Attach a screenshot if possible.

We may suppose that ways near each other that have not been connected before are not connected on purpose. So we should keep them apart when editing. Inserting a node into one way should insert that node into another way ONLY if both ways have shared the exact segment before.

I think JOSM shows that it will add the node to multiple ways by highliting them all. What would you expect to happen when you click in that situation? Maybe you can attach a small example osm file?

Screenshot

Screenshot attached. The mouse pointer is located not between the highway and the boundary way, but exactly on the highway (way 197516897), as confirmed in the status bar on the bottom. When I click, JOSM inserts a node into the highway (correctly) AND modifies the boundary way 73345823 nearby.

[GerdP]

Ah, I didn't notice that only one way is shown in the status line when possibly multiple ways are highlighted. Besides that you are right, the wanted action is probably never to connect those ways when they are parallel. A different situation would be when ways are crossing and you want to add the connection.

Have this / similar issue to the extend that the second close-by way will snap connect to the way where the node is place. Happens on ways and closed ways too (polygons)
