Photoshop CC 2017.0.1 20161130.r.29 unusable for 3 minutes after drag-drop layers from another document!

As you see it's your node server is in a wait queue and CC Libraries frontend also. So it seems I have nothing to do with GPU drivers (also it's up to date)

Here is Drag&Dropped layers asset
https://adobe.ly/2nEW8c2

How to reproduce:
1) Ensure that File > Generate > Image Assets is active and assets are generating.

2) Choose any layer ant the bottom of Icons artboard.

3.a) Try to drag&drop a layer group that causes the regeneration of all assets in all artboards. I've figured out it's something with a color or pattern layer clipped by another layer. 



3.b) Try to Alt+drag&drop layer from CC Library panel with the same composition as mentioned above.

4) Then undo it or delete dropped piece.

5) After several times PS becomes irresponsive because of node.js processing.
