Wing Pro 7: Print Function Execution Is Inconsistent

edit

When debugging/stepping over line by line, the first print can always print without any issue. However, from the second print on, none will print until the end of the script. When the last line finished and is executed, the Debug I/O finally prints the missing lines all at once. This seems like a bug for me.

Here's the code example

print("First line prints without any problem")
print("From this line on...")
print("Nothing prints")
print("Until the end of this script/line is executed")

Here are the software/OS versions

1. Python exe: 3.8.5
2. OS: Windows 10 Pro
3. Wing Pro 7.1.3.2 (rev 3600c9873c6f)

Some of my findings:

1. The same issue perists when using different Python 3 (3.7.x) with the same Wing Pro (7.1.3.2) on the same OS (Windows 10 Pro)
2. The same issue doesn't exist with WingIDE6.1 on the same OS (Windows 10 Pro)
3. The same issue doesn't exist on my Macbook Pro (macOS Catalina 10.15.6) with Wing Pro 7.1.3.1 (rev 3b2ed12a0484)
