Bug or Expected? - Via behaviour when moving trace segment between layers

In the attached video:

Put down two vias on either side of a resistor, tracks to each of the vias.

If I delete either track, the corresponding via stays.

If I select the track and change it's layer from Top to Bottom, the associated via vanishes.

If I "lock" the via, delete the track the via stays

If I then select the track and change it's layer, the via again disappears even though it's locked.

Not sure why deleting a track segment allows the via to stay, yet moving the segment to another layer causes the via to disappear?

I would have expected that the lock should have saved the via at least.

Bug or expected?
