Problem
Terminology crashes (SIGSEGV) when resized down when running neovim.
How to reproduce
- Open terminology (I'm on commit 99da684d8159462e2b8980c56f2400525aeebe40)
- From the interactive shell, open something like vim or neovim (I can systematically reproduce with neovim)
- Resize down to (0,0).
Backtrace
