[Bug]: Agent avatars not displaying in Pinned Agents sidebar (R2 Storage)

[RedwindA]

What happened?

Agent avatars fail to load in the "Pinned Agents" sidebar (left panel) and show as broken/empty icons. However, the exact same avatars display correctly within the Agent Buider.

When inspecting the network tab, the requests for these avatar images from the sidebar are returning NS_BINDING_ABORTED. It seems like the image requests are being triggered but cancelled or failing specifically in the sidebar context, while the R2 signed URLs work fine in the editor view.

Steps to Reproduce

1. Configure LibreChat to use Cloudflare R2 for image storage.
2. Create an Agent and upload an avatar image in the Agent Builder.
3. Pin the Agent so it appears in the left-hand sidebar.
4. Observe the sidebar: the avatar icon is missing or broken.
5. Open the Agent Builder for the same agent: the avatar displays correctly.
