Screenshot of IntelliJ IDEA Community package in Discover

SUMMARY
When viewing a package in Discover (in my example, IntelliJ IDEA Community Flatpak) that has few pictures, there is no scroll area for the pictures.

However, the button to scroll to the next position within the scroll area still exists. Clicking the button removes it and adds a button to scroll to the previous position, which functions similarly.

STEPS TO REPRODUCE
1. Open discover on a large display
2. Open the description for IntelliJ IDEA Community

OBSERVED RESULT
Button exists

EXPECTED RESULT
No button

Only show screenshot arrow buttons when the view is visibly scrollable

This does not affect the popup, where we always want to show the arrow
buttons because only one screenshot is visible at a time.
FIXED-IN: 5.23
