I tried to revert #29935, then it works well.
So I think it is caused by #29935. Maybe we should not add timeline-avatar-offset class in this case

Before 29935, see #29934, I do not think 29935 is directly related. 29935 is written to fix the bug described by #29934

Maybe it needs more code to check different cases.

I'm confusing which is right.
And why reviews should have timeline-avatar-offset.
It seems that it comes from https://github.com/go-gitea/gitea/pull/24526/files#r1188069927

It is used for this case?

In github:

Maybe adjust the direction of "speech bubble" is much easier than adding these complex conditions.
