Steps to reproduce:

1. On a version of Windows that contains the win32 calculator such as Windows 7 or Windows 8.1 or Windows 10 LTSC, open calculator (calc.exe).
2. Type a calculation and press enter.

Actual behavior:

NVDA is one result behind, so if I type 5+4, NVDA will speak 4 when I press enter, and I have to press the read current line command to hear the correct result, 9.

Expected behavior:

NVDA should speak the displayed result without having to read the current line.
