ClangFormat formats although only copy is intended (Ctrl+Alt+DownArrow)

1. Open e.g. codecompletionsextractor-test.cpp
2. Put the cursor on the line that declares/defines the member "Document briefCommentDocument"
3. Hit Ctrl+Alt+DownArrow to get a copy of that line in the next line
   ==> The copy is formatted and thus takes up 5 lines, instead of 1 as above:

    Document briefCommentDocument{Utf8StringLiteral(TESTDATA_DIR"/complete_extractor_brief_comment.cpp"), compilationArguments, {},  documents};
    Document briefCommentDocument{
        Utf8StringLiteral(TESTDATA_DIR "/complete_extractor_brief_comment.cpp"),
        compilationArguments,
        {},
        documents};

I think that when using this functionality, no formatting is intended, only indentation if at all.
