Black mold in bathroom, how to fix damaged drywall?

I have been removing the wallpaper from a bathroom and as I was peeling off the section near the edge of the ceiling, I saw some of the ceiling paint bubbling. I scraped some off to find black mold.

I cleaned the mold with a vinegar solution.

My question is what is the next step? Should I paint the damaged area with anti-mold primer or use something like Zinsser Gardz to seal the damaged drywall? Is there a product that does both? Then skim coat?

Up to you... I would cut it out and replace it. If the front looks like that, the back is probably worse.

If it feels solid I'd probably coat it with an oil base primer and mud as needed BUT if it feels the least bit soft I'd cut it out like X said.
