Godot: Strange lock behavior

[toby3d]

Operating system or device - Godot version: Linux Mint XFCE 18.2 (64_86x), Godot Engine 3.0.alpha.custom_build (8b362b50)
Issue description: While editing the skeleton, I encountered a strange behavior of blocking nodes, an example in GIF (look at leg_left and leg_right):

The problem disappears after the editor is reloaded (completely close / kill the process and start again). But it manifests itself again after some time of the editor's continuous work. A bug can occur more than once in the same scene (2 random nodes, 4 nodes, 6 nodes, and so on).

The lock is disabled on the editor too or just the icon?

@eon-s I just encountered this bug again. Yes, this behavior locks the nodes.

Can you attach a project that has this problem? Or if you don't want to make it public send it to me? (my email address is on my github page)

Can reproduce with ease:
1) Create a root node (any type), and a child node (CanvasItem, thus Node2D or Control)
2) Lock the child
3) Duplicate the locked child
4) Unlock or lock the duplicate -> both are locked/unlocked together

The issue seems to be that the metadata dictionary is shared.

Ah, I did not catch that the nodes needed to be duplicated for the effect to become visible. Thanks.
