Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd]
Windows Terminal version (if applicable): master 9ce884c4

Any other software?

Steps to reproduce

This is in ConHost and Terminal.

1. generate output (run dir then dir /?)
2. using NVDA get the current line
3. scroll up a few lines
4. use NVDA to read the previous line
5. repeat step 4 until you're on the last visible line
6. use NVDA to read the next line

Expected behavior

Reads the next line.

Actual behavior

Refuses to read the next line because you are "at the bottom".
