After we changed how Wikidiff2 handles add and remove operations, empty lines are often matched wrongly. It's technically not really a regression but the issue is more visible after the changes we've made.
One solution would be to treat an empty line as part of the previous paragraph. We need to take a look at the code whether this is possible.
Here's an example where one newline has been removed in the second line.

[WIP] Associate new lines with upper paragraph
It turned out that treating newlines of the previous paragraph did solve all the problems we could think of, but it created equally many in other situations. Therefore we are abandoning this attempt.
