Steps to reproduce
- Open Gerrit, click the bottom link "New UI", click any patch with many line comments
The line comments were folded in the old UI, except the most recent ones. This is good behavior, when you first see some patch and want to get general overlook, what was done (patches), what was discussed (comments, line comments), what were ratings from reviewers or jenkins bot.
In Polygerrit these are unfolded. This accentuates the line comments over other history of patch. But these comments can be already solved or answerred, so accentuation of the older ones doesn't make sense.
