The sentence I'm thinking of that worked in IT7 but now doesn't is: "She used to help with housework including groceries, cooking, laundry, and cleaning."
In this example, IT7 used to do the continuation with no issue, keeping the first line in the table highlighted so I could expand the next couple of words again and again until it was done. In IT9, however, as soon as the continuation hits a comma, it stops and the highlight disappears. I have to press shift to highlight the top line again to keep going.
