Took me a couple of hours to see that this was the issue I was having. Please include this PR asap.

I am experiencing the same issue, however while using `fzf`, which is also using popup windows by default. No matter if I use the vim9 bundled version via `packadd` or...

Just tried the fix posted by @damiendart - it indeed solved the scrolling issue after closing floating fzf windows!
