A pager, editor, or other full-screen program owned the pane, so matching was suppressed for as long as it did.

tmux fills that grid without adding to history, so what a capture
returns is the program's paint rather than anything the pane
printed — matching it reports text that was never written. Read the
screen with ``Server/capture(_:includingHistory:)`` instead of retrying: a
different pattern does not change what the wait is allowed to see.
