You’re right, we’re using Discourse 3.2.3. I thought I understood from this post that the problem also exists in version 3.3 but yours looks good. I’ll check if it’s possible for us to upgrade to 3.3, or maybe install an older version of the brand-header component.
Is it published somewhere that the component requires version 3.3? I don’t see that anywhere.
Do you happen to know when the updates were made that depend on 3.3? Or what the last version that works with 3.2 might be?
