Rows for the session's first window.

A detached session has no client to take its size from, so tmux gives it
80x24 and every program in it formats to that. Nothing can widen it
afterwards except `Window.resize`, and a width-aware program has already
truncated its output by then rather than wrapped it.

tmux 3.2 ignores both for a detached session and gives 80x24 anyway;
3.3 is the first release that honours them.
