Actor.h has a large comment that describes the entire lifecycle of Actors, which was written for the API website (https://docs.unrealengine.com/en-US/API/Runtime/Engine/GameFramework/AActor/index.html) and programmers. But, this entire comment shows up in the editor when you hover over that class, which is very distracting. It should only show this detailed information in the advanced tooltip
This is related to [Link Removed] and one possible fix is to change how the advanced tooltip system works to better integrate code comments, and breaking the initial tooltip to stop after the first paragraph as denoted by @note or other markup in the header
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-114903 in the post.
