I reproduced the issue, i.e. not being able to scroll beyond the first application window in "Show Applications", by installing the 20.04.1 ISO in a VirtualBox VM. I accomplished the installation without downloading upgraded packages, so it was a true vanilla Ubuntu 20.04.1 installation.
Then I updated all packages and rebooted, but the issue was still there.
Then I uninstalled gnome-shell-extension-ubuntu-dock and rebooted, and now the "Show Applications" scrolling worked as expected.
Finally I reinstalled gnome-shell-extension-ubuntu-dock and rebooted, and the issue was back.
So it seems to be something with gnome-shell-extension-ubuntu-dock. Btw, I used an external USB connected mouse.
Shouldn't the importance of this bug be raised? After all it's about a core feature of the Ubuntu desktop.
