Activity elements ordering is confusing

In the activity tab of pull requests, the order of elements is not correct. Indeed, when alternating updating the pull request with new commits and commenting on it, one would expect to have this alternance in the activiy tab.

Instead, the activity tab will show all the changesets added to the pull request on a given day, and then only all comments.

For example, with changes added to the pull request on October 19, 10:00 (changeset1), October 19, 16:00 (changeset2) and October 20, 12:00 (changeset3), and with comments added October 19, 12:00 (comment1), 14:00 (comment2) and October 20, 10:00 (comment3) and 14:00 (comment4).

The expected activity tab would show (most recent first):

• comment4
• changeset3
• comment3
• changeset2
• comment2
• comment1
• changeset1

Instead, it shows:

• comment4
• comment3
• changeset3
• comment2
• comment1
• changeset2
• changeset1
