2.0.0-beta.15: A few latest() bugs

https://stackblitz.com/edit/solidjs-templates-xxkqgjv6?file=src%2FApp.tsx

import { createMemo, createSignal, isPending, latest, Loading } from 'solid-js';

export default function App() {
  const [count, setCount] = createSignal(0);
  const asyncValue = createMemo(async () => {
    const c = count();
    await new Promise((resolve) => setTimeout(resolve, 1000));
    return `Async Value ${c}`;
  });

  const asyncValue2 = createMemo(async () => {
    const c = count();
    await new Promise((resolve) => setTimeout(resolve, 5000));
    return `Async Value 2 ${c}`;
  });

  return (
    <Loading fallback="Loading...">
      <button onClick={() => setCount(count() + 1)}>Click me</button>
      <p style={{ opacity: isPending(count) ? 0.5 : 1 }}>Count: {count()}</p>
      <p style={{ opacity: isPending(() => latest(asyncValue)) ? 0.5 : 1 }}>
        Latest Async Value: {latest(asyncValue)}
      </p>
      <p style={{ opacity: isPending(asyncValue2) ? 0.5 : 1 }}>
        Async Value 2: {asyncValue2()}
      </p>
    </Loading>
  );
}

1. On initial Load {latest(asyncValue)} is undefined
2. First click of the button doesn't make isPending(() => latest(asyncValue)) to true
3. Second click of the button makes it go pending, but I expected it to clear earlier
