[New-bugs-announce] [issue40591] \r broken in IDLE

[wyz23x2]

New submission from wyz23x2 <wyz23x2 at 163.com>:

When you run this code:

import time
for i in range(10):
    print(f"\r{i}", end='', flush=True)
    time.sleep(1)
print('\n')

On CMD it prints 0 at the first time, then it will erase it and print the increased i. But on IDLE it just prints "0123456789" -- that isn't right.
