CombineMeshes() bug in 2019

Hi, I reported a bug that appeared in 2019.1.0a5 a while back related to Mesh.CombineMeshes(). Unity QA was able to reproduce and indicated it was a regression as it worked fine in 2018 and earlier.

I just thought I'd post it here to get more visibility in case others have run into it as well. If so, please use the link below to see more details and upvote the issue to see if we can prioritize it higher for a fix.
