bug/feature interpretation "control after generate"

I am fairly new with using comfyui. But what annoys me is that when I generate images, found one and want to tune my prompt on that version, clicking fixed also requires me to copy the seed.

This is not logical to me. I would assume if I switch from random to fixed I don't need to do anything any more, and the seed stays like the last generated image.

The issue names no file, test, or entry point. Start by tracing the frontend controls for switching from random to fixed seed after generation, then verify that fixing the seed preserves the last generated image's seed without manual copying.
