Seems to be the same as #12672 |

#12672 at the time of writing this post still uses |

Looks like this also needs a test for the use case that was causing the original issue? |

Sure, I can put one in later. Thought that since we used existing helper we didn’t need one, but probably best to add that test case.

You want a test that tests the scatter use cases so no one inadvertently breaks this functionaility in the future by modifying your check. The API is quite flexible (some might say too flexible) and its hard to anticipate every usecase when making changes, so we hope the tests catch them. |
with non-0 starting index.

How does this look? 2 new test cases added, fixed a an easy formatting line on the way. Borrowed the empty test case from @timhoffm. The other test case is for the non-zero indexed |

Sure, let me look into it tonight.

Owee, I'm MrMeeseeks, Look at me. There seem to be a conflict, please backport manually. Here are approximate instructions:
And apply the correct labels and milestones. Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon! If these instruction are inaccurate, feel free to suggest an improvement. |

Thanks @phobson. Is there anything I need to do about the backport comment posted by the bot? Happy to take this over the finish line. |

Trying to backport this currently fails the tests for 3.5. See #12761. |
