They should be addressed if possible. By simply disabling these calls, I noticed these issues:

- When scrolling up very quickly, the first card goes entirely below the fold instead of stopping and peeking.
- When discarding snippets, the bottom spacing does not shrink to the necessary minimum. It is possible to scroll way down instead of keeping the first card visible.

Rest seems to behave fine (including the header).
