I have some HTML content above Discourse’s header, which is about 90px tall.

When I scroll, the sidebar’s top position still takes this custom header’s height into account until I stop scrolling, then it properly recalculates its position. It happens every time we scroll.

Better seen than explained:

Not breaking, but slightly inelegant.

Until it’s fixed, I’d be happy to know if there’s any CSS or JS trick that would make this issue disappear 🙂
