Keyboard shortcut scrolling issue: When using the j or k keyboard shortcuts to navigate between posts, the view does not account for the fixed header, causing issues. For small posts, the view scrolls too much, hiding the beginning under the header. For large posts, the view centers the selected post, making it difficult to read. A proposed solution is to position the selected post at the top of the screen instead of centering it. FichteFoll and Falco have demonstrated this issue with example posts.
Interestingly, small posts (including the one I linked) actually do scroll the view to the top but scroll too much so that the beginning is hidden under the fixed header. This is mostly noticable when scrollung upward with k.
Scrolling with j is only an issue for large posts, like yours, where it’s completely broken, or mine, where it’s not as broken but still not right.
