Environment

Windows build number: 10.0.20197.0
Windows Terminal version: 1.2.2381.0

Steps to reproduce

  1. Open Windows Terminal
  2. Press alt+shift+- (or whatever keybinding is set for this) to open a second horizontal pane
  3. Build and run this TerminalStress application in the bottom pane.
  4. While the stress test is running, press alt+shift+down arrow key to reduce the size of the pane. Repeat until the pane is reduced to the smallest possible height.
  5. Press and hold alt+shift+up arrow key to grow the size of the pane upwards.

Expected behavior

The terminal does not crash.

Actual behavior

The terminal crashes (FAST_FAIL_FATAL_APP_EXIT) in TerminalControl!TextBuffer::InsertCharacter+0x1fc [E:\BA\167\s\src\buffer\out\textBuffer.cpp @ 401]
