Notes posted in discussion always appear at the top when sorting by "last update"

[syzyxy]

When sorting entries by the "last update" field, any "Notes" posted by mappers/modders always appear at the top of the list, regardless of their actual update timestamp. This behavior might not align with expected sorting behavior, where all items are sorted strictly by the "last update" value.

One example: https://osu.ppy.sh/beatmapsets/2257774/discussion/4804041/timeline/total
You have to scroll down a bit in order to see actual latest updates which is rather quite annoying.

I'm not sure if this issue has been reported here before. While it's usually not a major annoyance, the inconsistency becomes apparent when compared to the "timeline" sorting, which doesn't exhibit this behavior. Since there's no clear need for this inconsistency, aligning the behavior across sorting methods would likely improve the user experience.
