wireframe: highlight member nodes when relation is selected

[skyper]

What steps will reproduce the problem?

1. select a relation with at least on node as member
2. See the node nicely been highlighted in pink
3. switch to wireframe

What is the expected result?

The node is still somehow highlighted

What happens instead?

Only ways are highlighted but not nodes

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

If we simply highlight the outline in red (same colour as ways) we would still have a different rendering as selected nodes as the later are rendered solid and not just the outline.
