In this major bug ticket : [SONAR-15952] New code detection when using reference branch and rebasing doesn't detect some commits on branch - SonarSource we can read :
" The issue was definitely fixed in SonarQube 9.4 (see
SONAR-14929 and SONAR-15697) and is not planned to be backported to 8.9 LTS."
This is a big disappointment because we were waiting for it. I guess it requires some work to backport it, but isn’t it the purpose of LTS versions to receive all major fixes ?
