Spurious conflicts with identical sides #356

While rebasing a branch in mergiraf itself, I got a conflict with identical sides: ``` <<<<<<< HEAD ) -> (ParsedMerge<'static>, MergeResult) { ||||||| parent of e81a230 (refactor: move syntax checking from line_based.rs to merge_result.rs) ) -> MergeResult { ======= ) -> MergeResult { >>>>>>> e81a230 (refactor: move syntax checking from line_based.rs to merge_result.rs) ``` Running `mergiraf solve` also doesn't resolve the conflict. I'd like to investigate why it doesn't get resolved automatically in favour of the `HEAD` version. It might be a duplicate of an existing issue though. This happened with the current `main` version of mergiraf (commit b95da604328bf2cecf619f2bea6f62401c5749f).
