Grabbing/dragging a layer from a transparent pixel

Back in CS5, if you held cmd/ctrl to quick-grab/drag the contents of the working layer, you could grab anywhere in the layer, or at least anywhere in the bounding box, and it would drag the whole layer/selection.  This worked even if the point you clicked on was transparent in the currently selected layer.  Iirc, this was also basic behavior on the move tool when selected normally.  I could have sworn it behaved this way even fairly recently in CC, to the extent that I've been using CC on occasion at work and as a floating license on my travel laptop.

My main desktop on which I was still nursing my old CS5 license finally gave out, so now I'm on CC across the board, and one of the first things I noticed while trying to work with a document containing many sparse but precisely pixel-aligned layers is that whenever I tried to grab layer content by a transparent pixel, rather than moving the current layer, it would instead change layers, selecting the topmost one with opaque content and move THAT one rather than the one I was actually working in.  This is a major workflow impediment when working with e.g. spritesheets or tilesheets where a great many layers may only contain a handful of pixels representing small variations between frames, where it's not always obvious which pixels belong to the current layer, let alone easy to grab them once located, and where grabbing/moving anything but the intended content is guaranteed to throw the whole sheet out of alignment.

Is this simply the new permanent behavior of the tool, or is there an option to revert it to the classic behavior?  If there is an option, where among the hundreds of preferences is the option located?
