This example (use it in `examples.py` will make the problem evident: ``` def example_99(): emit.message("Begin") for _ in range(10): emit.progress("Middle message that will be repeated...") time.sleep(5) emit.message("End") ``` There the same message is emitted over and over again, with a time elapsed between. This is a normal case where some polling is done to see if a process finished, while showing a message on every check (Charmcraft itself suffers this when polling the Store after an upload). The effect is that initially the middle message appears, and after a couple of seconds the spinner and time counter is shown. Some seconds later the middle message is emitted *again*, and the spinner and time counter disappears, only to appear again after another couple of seconds. What should happen is that if the *same message* is emitted again, it should not hide the previous spinner and time counter (which should not be reset, of course).
