Copying from one cell and pasting to another, performed several times, gets slower and slower until it eventually leads to the "Unresponsive script" warning.
You can test in my sandbox if you want.
I'm getting this in both FF and Chrome.

Hmm, I think maybe the internalList isn't merging properly and is therefore doubling in size each time.

That is the problem. I think it is because newFromDocumentInsertion doesn't consolidate duplicate internal items. This is why we don't copy over the internal list to surface widgets, hence existing references are not available in image captions. Paging @Catrope.
