Threaded text: Flatten Transparency on a frame no longer duplicates its text

Browse Source 
Object › Flatten Transparency replaced a frame of threaded text by its
outlines with Convert All Text to Outlines, and by flat regions or an
image where the frame was transparent. The thread's re-flow then added
the frame's text to the story, as it does for a frame that was deleted,
so the other frames held that text a second time while the outlines,
regions or image drew it.

A frame that Flatten Transparency outlines or flattens now leaves its
thread with the text it shows, and the other frames keep the text they
hold, as with Create Outlines and Expand. When the thread's last frame
is flattened, the text it has no room for goes after the text of the
last frame that stays. A thread left with one frame is no longer a
thread, and undo restores the thread.
