Reordering of constraints and and elements doesn't work

[shyblower]

When I try to reorder constraints in the Assembly tree by dragging them with the mouse and dropping them before another constraint, the constraint after the dropped one gets replaced by the dropped one but the dropped one also remains in its original position. So I get the constrained I tried to reorder twice in the tree, like two tree items pointing to the same constraint object while the constraint after the dropped one is removed. When I try to remove one of the duplicated constraint items, both disappear from the tree.

The same goes for the elements list inside the assembly tree.

I'm experiencing this when using the latest LinkMerge prerelease build from your Link Branch.

It's btw. the same with the 220709 LinkDaily release.

Reordering parts and items outside an Assembly3 subtree works, though.

The "move item up/down" functionality from the Assembly 3 menu and toolbar works correctly and does what I tried to achieve with reordering.

Is this a known problem and the reason why the "move item up/down" (asm3CmdUp and asm3CmdDown) functionality exists?
