Accessibility: jumps in review

[codeofdusk]

Environment

Windows build number: [run [Environment]::OSVersion for powershell, or ver for cmd]: 1909 (18363.720)

Windows Terminal version (if applicable): Terminal as of 5bcf0fc.

Any other software? NVDA, Narrator.

Steps to reproduce

1. type:

echo 1
echo 2
echo 3

2. Using NVDA with Windows Terminal support or Narrator, review a few previous lines of output. You should see the prompt, then 3, 2, 1.
3. wait about three seconds.
4. Try to review previous line again.

Expected behavior

The screen reader keeps its position, reporting "2" for example if the last-reviewed line was "3".

Actual behavior

The screen reader reads the prompt again, then starts back over with 3, almost as if the cursor bounced back.

This cursor bouncing does not occur in open console (that works as expected).
