One step forward and one back, net a little bit better. 
 
I only use Photoshop for Focus Stacking. Prior to 9.3 it was a pain to try to find the stacked image after returning to Lightroom. Nice fix in 9.3. 
 
But prior to 9.3, choosing the Crop tool and clicking Constrain Crop would crop the image inside the left over mess on the edges. 
 
So for me, an overall improvement.

A detailed step-by-step workflow would be great here. Can you give us exact instructions starting before you sent the files to Photoshop?

Here is my workflow. Aside, the image alignment is terrific, eliminating the need for a tripod even when viewed at 100% on a 4K monitor. Credit where due, this was derived from a Scott Kelby tutorial.
 
Lightroom: 
  - Select the images that you wish to stack
  - Photo menu 
    - Edit in 
    - Open as Layers in Photoshop 
 
Photoshop: 
  - Wait for the images to load
  - Select the images to be stacked
  - Edit / Auto Align Layers 
    - check Auto
    - OK 
    - wait for spinning wheel to stop 
  - Edit / Auto Blend Layers 
    - check Stack Images 
    - check Seamless Tones and Colors 
    - OK 
    - wait for progress bar to complete 
  -File Menu 
    - Save 
    - wait for progress bar to complete at the bottom left of the window 
 
Lightroom 
  - Develop module 
  - click Crop tool 
  - click Constrain to Image box
 
See the white bar along the top and left top corner, you might have to open this in an editor to see the bar as white on a white background doesn't show. Sure wish this forum application allowed a couple of the Gmail like tools for colors and background. Prior to 9.3, choosing Constrain to Image automatically cropped this out of the image which I thought was like magic. As I'm almost always going to crop the image anyway, it is not a big issue for me.

Really? AFAIK, 'constrain to image' works when you rotate the image, not just by clicking it.

Always worked before upon returning a stacked image from Photoshop.

Johan,

If you create a pano in Lightroom and reimport the UNCROPPED DNG into Lightroom all you have to do it hit Crop and then Constrain to Image and it will automatically crop inside the image pixels without having to rotate.  I don't know if this works or not when importing a focus stack from Photoshop.

Hello, they do not speak about Pano here, meais of a focus-stacking in PS.... Therefore not back there. DNG!

Johan, you are non-connected with the topic.
