Environment

Windows build number: Win32NT 10.0.18362.0
Windows Terminal version (if applicable): 0.5.2762.0

Steps to reproduce

ssh to a Linux box.

Get Markus Kuhn's UTF-8 decoder capability and stress test file.

cat UTF-8-test.txt

Expected behavior

Consistent output (which, by the way, reasonably closely matches what's described in the file), regardless of timing, including with various parameters to slowcat.

Actual behavior

Faulty and inconsistent output, presumably depending on the timing of events.

Often the output terminates way too prematurely, e.g. during the intro or section 1 or 2 of the file. Sometimes the succeeding shell prompt isn't printed either, although the shell is already ready to accept a new command.

Other times the output ends as the end of the text file, but as you scroll back you'll notice that a big chunk is missing.
