Non-existing item ID error when loading multiple-image HEIFs
GIMP version: 2.10.2
Operating System: Ubuntu 18.04
Package: flatpak
Description of the bug
HEIF files with multiple images give the error "Usage error: Non-existing item ID referenced." https://nokiatech.github.io/heif/content/images/random_collection_1440x960.heic https://nokiatech.github.io/heif/content/images/season_collection_1440x960.heic
The same images work without error in the original upstream plugin (https://github.com/strukturag/heif-gimp-plugin).
