Batch: Save As.... Avoid asking me to save when closing original?

I do something similar using an Action.
Photoshop NEVER used to ask me if I wanted to save the original before closing it.
It has been resized and saved elsewhere via the Action.
This has started happening after the latest update 27.6.0. Annoying. 
I don’t have a solution apart from adding a step to the end of the Action where I close the image and clink no to saving it before closing.  
I sometimes don’t want to close the image so this is not 100% ideal.
Have tried checking and unchecking Enable legacy “Save As” in Preferences. Makes no difference. 

The batch command uses an action. So look at the action steps, where a close without saving command could be used.

That being said, this was my Batch action setup from that old topic:

I created a batch script here (currently at v1.8):

That would likely require a scripting solution. Do a search, I believe there is a script that extends Image Processor to add webp.
