This issue was fixed a little while back, Steam Stable (1757650573) and Beta (1758671554) release. https://github.com/ValveSoftware/steam-for-linux/issues/11814 is however still valid as the Store Page's gallery will still ocassionally fail to register gamepad input.
Your system information
Please describe your issue in as much detail as possible:
After having viewed an image carousel on a title's Store Page, pressing B to back out of it will cause the user to be return to the page prior to the Store Page. You therefore don't have a way of closing the image carousel without first leaving and returning to the Store Page.
EDIT: This also affects news entries under the Recent Events & Announcements section on store page.
