Windows build number: 10.0.19041.329
Windows Terminal version (if applicable): 1.0.1401.0

Any other software? no

Steps to reproduce

Cannot reproduce on demand, but I know it occurred after dragging the window to a new size (number of rows and columns.)

Expected behavior

I was in a Command Prompt, using the Up Arrow to recall my command history.
I expected the recalled commands to appear on the current command line.

Actual behavior

The FIRST command recalled appeared on the current command line, subsequently recalled commands (I pressed Up Arrow more than once) appeared one row above but indented as if after a prompt (though the line above was previously blank.)

FWIW, this is not the first issue I've seen after resizing the window, but almost all of them go away after another resize and do not return if I try to return to the previous size and test for them. So the triggers are difficult to define, sorry. Hopefully this will at least warrant some comments near where this is handled, just in case something is noticed in the code. :-)
