3 days ago 9087505-zd-a8c the merchant reports the issue is also present using the Twenty Sixteen theme. I was able to replicate this with TT4, noticed it started happening at 200 categories in. And it happens both for updating and creating products.

To Reproduce
Steps to reproduce the behavior:
Instead of assigning the single category I selected, all categories starting with 12 are assigned.
Screenshots

Only the category I select should be applied.
