In https://github.com/bytecodealliance/wasmtime/pull/11620 I ported the preview1_file_write.rs test from WASIp1 to WASIp3 but running it fails:

$ cargo test -p wasmtime-wasi --features p3 --test all -- --exact p3::p3_file_write --nocapture
...

running 1 test
preopen: TempDir { path: "/tmp/wasi_components_p3_file_write.component_6vHcas" }
