[Bug]: Batch size in img2img does not work properly with Poor man's outpainting

Is there an existing issue for this?

[X] I have searched the existing issues and checked the recent builds/commits

What happened?

When you attempt to increase the batch size beyond 1 while performing outpainting using Poor man's outpainting, only one image result will be shown and saved to disk regardless of how much numbers you put. I read about the same issue happened to outpainting mk2 and solved already so hope it can be solved too for this Poor man's outpainting, since it is doing better generation for me than mk2.

Steps to reproduce the problem

Go to the img2img tab
Upload an image
Increase the batch size to 2 or more
Under scripts, Poor man's outpainting
Generate

What should have happened?

The amount of generation images should be according to the set up batch size, and not only outputting one image all the time.
