Photoshop: Problem Resizing Canvas when Artboards are Used

I see several issues with Artboard resizing that have come up in this community, but never exactly this one.
When using Artboards, resizing a canvas down in size (for example, an image 156px tall to 78px tall), the result is that we get the expected "The new canvas size is smaller than the current canvas size; some clipping will occur", but then instead of ending up with a 78px tall canvas, we get a resulting 316px tall canvas (2X156)! When trying this again - using 78px as the measurement, the height suddenly doubles again - to 632 px tall!
This problem doesn't occur when creating a file that doesn't utilize artboards, but it's consistent and repeatable when artboards are in use.

I don't think you're supposed to be using the Canvas Size function to resize an artboard. Have you tried using the Artboard Tool?

Thanks for this. I'd actually posted this in response to a problem someone else was having - believing it was a bug. My artboard tool does work fine, and I don't know about that of the original poster. I'll check with him to find out. 
Seems to me though - that since we can now make entire documents that are based on Artboards, the Canvas resizing would/should work for the whole document, since the artboard becomes, essentially, the canvas.
Good call, eartho - I hadn't suggested that to the first person to bring it up to me! Thanks!

Artboards are meant to be separate entities from the canvas because you can have one or many, and all live within the one global canvas. By default, the canvas is padded with space automatically when you make Artboards.
I am going from memory here but...
Try selecting the Artboards tool and looking at the options in the tool menu bar at the top (gear icon I think?). First, uncheck auto-size to stop the canvas from resizing everytime you change or add Artboards. And in the latest version there is a shrink wrap option that should fix the exact issue you are having.

Thank you. I appreciate the response - and you're absolutely right. I'm actually leaving this up here as a feature request now, since this is where the feature request form resides - perhaps I can change the title to reflect that. - NOPE can't change it's nature. I'll repost as a feature request.
