This doesn't lead to a failure right now so isn't critical, right? |

Well it was leading to a failure. Did they change? |

It's only not failing because we're not running the doctests. The test case
here would presumably fail on some platforms. So if you want it to be
critical, we can add the test case without the fix :p

LGTM as well, indeed it's useful to merge for 0.20 because of #12014. |

MeanShift is undeterministic if intensities of clusters are the same. This uses the cluster center values to sort in case of a tie.
