Exactly that. You usually have CI on 3 levels (possibly with increasing
complexity on e.g. compilers tested):

1. PRs
2. develop
3. master

Why is the 2nd stage required? Assume you have 2 MRs. The first
introduces a new file using some existing functionality. The 2nd
changes/removes/renames that existing functionality and all references.
Both MRs pass CI and are merged. But now your develop is broken as the
update from the 2nd was not applied to the feature in the 1st. Another
commit (possibly directly to develop) fixes this after which CI passes.
Now you can put this into master.
