Tasks are still running on main thread

[daBlesr]

Hello, I tried creating computationally intensive tasks on wasm web, on separate threads using:

use std::thread;
use async_task::Task;
use bevy::tasks::futures::{check_ready, now_or_never};
use web_task::{spawn};

let task: Task<Option<NavigationPath>> = spawn(async move {
  let current_thread = thread::current();
  info!(
      "Pathfinding is running on thread: name={:?}, id={:?}",
      current_thread.name(),
      current_thread.id()
  );
  let guard = obs_clone.read();
  if let Ok(obstacles) = guard.as_ref() {
      compute_path_towards(&*obstacles, pos, &target_clone, CELL_SIZE)
  } else {
      None
  }
});

but it keeps printing "main" thread. I was thinking the purpose of this library is to specifically that right? Am I doing it wrong?
