In both stacks, the `Terminal` `_buffer` isn't initialized yet.

Looks like another instance of "terminal connections that produce output too quickly cause us to beef it", possibly related to recent initialization order changes!

I was working on https://github.com/microsoft/terminal/issues/11021 and was going crazy that with a refactor things crashed trying to open a debug tab. I guess I was just sufficiently unlucky that it worked when I had the old code checked out and didn't work when I was trying to test mine.

Hmm. When this works, DebugTapConnection::Start is called, then DebugInputTapConnection::Start. When this doesn't work, only the Input one is called.

@zadjii-msft commented on GitHub (Oct 6, 2021): Hmm. When this works, `DebugTapConnection::Start` is called, _then_ `DebugInputTapConnection::Start`. When this doesn't work, only the Input one is called.
