Using "Add layer alignment target" with "Place auxillary axis" creates artifacts

Was this with on of the modern canvases or the legacy canvas? I cannot duplicate this behavior on 5.1.0-rc1-28-g605d0ab3c on Linux using either modern canvas.

With modern canvas, can still be reproduced.

Does not reproduce in Legacy Toolset.

It appears that there is a tool state issue at play here.

TOOL_MANAGER's event dispatch logic is having trouble when the activating tool and the deactivating tool are both states in the same TOOL_INTERACTIVE.

Two ACTIONs by the same TOOL_INTERACTIVE turned out to be a red herring. It was just some missing AF_ACTIVATE flags on the ACTIONs in question.
