* test: add pre-change snapshot of new-window event * move to .ts file for easier diff * refactor: improve feature string parsing logic * test: update snapshots * update type names per review * update comma-separated parse test * use for loop instead of reduce per review * tighten up types * avoid variable guest contents id returnValue in test snapshot
