align nodes in line moves outer instead of inner node

[skyper]

What steps will reproduce the problem?

1. select three nodes in a row all member of the same way (A-C)
2. align nodes in line

What is the expected result?

The middle node (B) is moved.

What happens instead?

The outer (top) node (C) is moved.

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

Similar happens if you select four node (A-C,K). Both outer nodes (C,K) are moved instead of the two inner ones.

Seems to me that #9605 was almost about the same issue. I understand that it might not be needed for three nodes as I could simply select the middle node but for four nodes this will not work. I need to define some fixed nodes which had been the two outer ones for quite some time.
