Terminal output only restored in horizontal term

[zbirenbaum]

Mostly a note for myself so I can track the issue and don't forget how to reproduce it. Should have a fix up tonight.

Steps:

1. Open vertical term
2. Run command that produces some output
3. Hide term
   4a. If open horizontal term: output is there
   4b. If open vertical term: output is missing

This doesn't seem to be an issue any longer as I couldn't reproduce it with the steps I wrote when I went to fix it. It may have been a upstream problem or something. I'll leave this open a little longer in case someone else notices something or I notice it again.
