First post ![1](https://global.discourse-cdn.com/meta/original/3X/e/f/ef9a490364da6fd9991f4cda699c91b94b5c9bb8.jpeg) We go to the last ![2](https://global.discourse-cdn.com/meta/original/3X/7/c/7c12882772810416eb8a4baa4d23fb0d451796f8.jpeg) [https://try.discourse.org/t/the-room-appreciation-topic/289/6](https://try.discourse.org/t/the-room-appreciation-topic/289/6) This is especially noticeable if you refresh the page. Something is wrong with the behavior. ---

Wasn’t this fixed recently? Regression? ---

That’s the normal behaviour of [the smart header](https://meta.discourse.org/t/smart-mobile-header/99846) (very new feature). When you are in the middle of a topic, the header shows a mini logo, the topic title and category, etc. instead of the website header. This way we know what topic we are being reading. * * * But when you are at the top of the page, it displays the site header (as the topic title should be visible, at the top of the page). And when you are at the very bottom of the page, and that you are no longer really in the topic, as are now in the **Suggested Topics** section, then here it also reverts to the site title. ---

Except that’s not strictly true, it only does it below certain browser widths. ---

I could not reproduce at first but indeed now if I go to your link and then I press End, it’s good but now I press F5 and indeed it’s no good (site title). Then I press End again and it’s back to good (topic title). This will certainly be improved, it’s a very very new (great) feature. ---

I am seeing the same thing, it looks like the mobile detection is not quite right. cc @Johani ---

Confirmed, we should not be triggering any of this code on desktop, we will get it fixed quickly. ---
