Discovered by accident, but it doesn’t seem to be expected behaviour, so I think it’s worth reporting?
When merging two documents into one, the word count of the second document seems to get added onto the session target, despite the fact that no new words are added and no text is changed.
Using the latest version (Beta 18), but as I discovered it by accident I can’t confirm whether it’s new to this version or a carry-over from previous ones. Apologies!
