touch command ignores cwd

[tugrulates]

Minimal example (bug.ts):

import $ from "@david/dax";

await $`rm -Rf *.txt test_dir`;
await $`mkdir -p test_dir`;
await $`touch 1.txt`.cwd("test_dir");
await $`echo > 2.txt`.cwd("test_dir");

console.log("./test_dir/ contents:");
await $`ls`.cwd("test_dir");

console.log("./ contents:");
await $`ls`;

> deno run -A bug.ts
./test_dir/ contents:
2.txt
./ contents:
1.txt           bug.ts          test_dir
