Potlatch 2.2 does not discard a way's first point when Undo-ing it

Click two or more points (=n'') on map - a way connecting clicked points is being created. After (''n-1) Undo's the way is gone, but the initial point still remains visible (a green dot) and the Undo button is already grayed out - one step got forgot.

It is possible to delete the point manually (red (x) button), but it should be also deleted by the ''n''-th Undo.

I observe this behaviour regularly. All that's needed is to create a two-node way and press undo once. This happens quite frequently when I try to drag the visible area but somehow P2 recognizes clicks instead of the drag. I think this is a major nuisance as it tends to create nonsensical empty nodes if you don't spot the problem and delete them manually. Does it break the undo system if such ghost objects are left over?

Fixed. Ow. That was a lot harder than I expected.

Thanks, it was indeed a frequent nuisance.

The misbehaviour is still/again there. Node cannot be deleted using either undo-button or ctrl-z

Yes. Although I submitted a pull request with the bug fix, it has not been accepted by the maintainer of Potlatch 2, Richard Fairhurst. I suggest you ask him politely about it.

#4406 seems a duplicate of this bug.
