Content Loader->Giveaway Groups fails to load groups for certain giveaways

[poetickatana]

Description When "Content Loader->Giveaway Groups" is enabled, the groups of certain giveaways fail to load. The problem appears to manifest itself only for giveaways aimed at specific groups. e.g. Giveaways for group "A" will have their groups loaded, but giveaways for group "B" or for groups "A & B" will not.

Steps to Reproduce

1. Enable ESGST setting 2.6.3 "Content Loader->Giveaway group".
2. Set ESGST setting 2.6.3.5 "Additional Options" to "Popout (On Click).
3. Go to a group's Giveaways page. (e.g. https://www.steamgifts.com/group/Kro1T/esgst)
4. Click on the group icons of various giveaway.
5. Certain giveaways will display their groups. Other will show "Loading content..." and a spinning circle indefinitely.

Expected Behavior The group list of a giveaway should appear almost instantly after clicking on the group icon.
