I have noticed that comments are expanded in a different way when I click "see more comments". For example, if an answer has 10 comments, on loading the page it shows only limited comments with a bottom view "View 4 more comments". But the comments are getting expanded in a non-linear manner as the hidden comments are being shown between the existing comments when I click "View 4 more comments". Is there any specific reason for that or is it designed in that manner?

2That's because the comments that appear when you click 'view x more comments' have less votes than the ones which you first see.– double-beepDec 30, 2019 at 11:40

4Somewhat related: meta.stackexchange.com/q/24490/282094 - It's not a Bug, nor will it be fixed. It's also agreed that it's annoying. --- Notice the name of the user, 10 years ago changed their name to protest. They were 1st!– RobDec 30, 2019 at 11:49

Does this answer your question? How does comment voting and flagging work?, and numbers of answers needed to cause collapsing.– RobDec 30, 2019 at 15:09

When there are many comments, only part of the comments are visible.
In attempt to show the most relevant comments, the sort is made by the comment score, then they take X top comments, where X is defined per site. (Maybe it's explained somewhere, but it's not the topic here.)
So, for example, when there are 8 comments total, with scores of 3, 6, 1, 0, 0, 7, 9, and 0, and the site showing only three comments, those with score 6, 7, and 9 will be visible by default. When expanded, the sort is only by date, so those comments with top score will "jump" into place.

6"the sort is made by the comment score" - they are filtered by the "comment score", but they are never actually sorted by it - they still remain in chronological order.– MrWhiteDec 30, 2019 at 15:23
