Yes, the set of those options is not complementary or compatible with their purpose, like using editor: true with readOnly: false or allowInsertColumn with an object dataset. With such a list of options that we have, there might be some that simply do not match. The issue here is that since v10.0.0, the highlight of those cells has remained, so it creates the idea that the data can actually be copied. I’ll do my best to track the change down and investigate it further.
