Eventually I discovered I can get it to work by locking bracket-lib to 0.8.1 (looks like something has changed between that and the latest 0.8.7). The Cargo.toml that works for me now has:
[dependencies]
bracket-lib = { version = "=0.8.1", default-features = false, features = ["crossterm"] }
bracket-terminal = { version = "=0.8.1", default-features = false }
