[Bug] Can't move origin box relative to layer with Ctrl pressed in version 1.3.16

When I try to move the origin box position over the layer, while I hold the left mouse button down over the green dot, with the cntrl button pressed, the box moves the position of the layer instead of moving over the layer. I never had this prob in earlier versions of Synfig.
Thank you.

I confirm, it seems this has changed between 1.3.11 and 1.3.12 :confused: (at least for origin of Group Layer)
