Bug: https://graph.microsoft.com/v1.0/search/query total is wrong when results include an externalItem

Question

Here is the request:

{
    "requests": [
        {
            "contentSources": [
                "/external/connections/*"
            ],
            "entityTypes": [
                "driveItem",
                "externalItem"
            ],
            "query": {
                "queryString": "presentation for client xyz"
            }
        }
    ]
}

And here is the response:

Notice how "total" is equal to 1 but its returned two results, one is external which I suspect is causing the issue
