Tools make use of selected but already deleted nodes

[alv]

The title may seem cryptic, but steps to reproduce:

• draw a unclosed way with four nodes
• select each node
• distribute nodes
• select one of the middle nodes
• delete that node
• using the select history on the right hand selection panel, select the first line that reads "4 nodes"
• you see three remaining (as in not deleted) nodes selected
• select distribute nodes

expected result:

• equal distances between the three nodes

result:

• no change, equal distance between all four nodes, including the deleted.

In fact, all (or many) tool actions work with the deleted nodes as if they still existed, when reselected in this manner. At least align in line, align in circle, orthogonalize (ways + two deleted nodes).
