Search shows only 75 results and the wrong page count at first

Summary

When I search something, only 75 results are shown and only 3 pages show at the bottom. When clicking on any other page, suddenly some more pages show up (but not the last possible page). If this process is repeated, then eventually the last page is shown and the result count is shown correctly.

Steps to reproduce

Search in a chat/community where there are considerable amount of messages (in my case >1K).

Environment (optional)

Latest desktop app, windows 11
