Environment

Windows build number: Microsoft Windows [Version 10.0.18363.720]
Windows Terminal version (if applicable): Version: 0.10.781.0

Steps to reproduce

Use terminal preview for a while, then type exit to close the current tab

Expected behavior

The tab closes. This happens sometimes, particularly on a recently opened tab that hasn't been used much

Actual behavior

A "process exited" message is printed but the tab remains.

c:\src>exit
[process exited with code 2]

I don't know what triggers this - I cannot repro it on demand. I'll watch for it.
