[2.0 next, regressed after rc.13] Production refresh remains pending after a settled computation (production build) #3888

Describe the bug

A production refresh stays pending even when its computation returns an already-resolved promise.

Steps to Reproduce the Bug or Issue

1. Use the source below with the selected Solid build (complete setup is linked above).

import { createMemo, createSignal, refresh, resolve } from "solid-js";
export default function App() {
  let calls = 0;
  const value = createMemo(() => Promise.resolve(++calls));
  const [result, setResult] = createSignal("idle");
  async function run() {
    await resolve(value); // The first computation has settled with 1.
    setResult("refreshing");
    setResult(String(await refresh(value))); // Production never reaches this write.
  }
  return (
    <>
      <button id="trigger" onClick={run}>
        Refresh
      </button>
      <output id="answer">{result()}</output>
    </>
  ); // Click: development shows 2; production remains refreshing.
}

2. Paste this App into a fresh Solid 2 app. Build for production, click Refresh, and wait at least 200 ms.

Expected behavior

Expected: The output becomes 2, as it does in development.
Actual: The output remains refreshing in production.

Platform

• Solid: solid-js / @solidjs/web next at 3086f1b77cd7b0431d3a7f768c2984c335758633; comparison 2.0.0-rc.13. Signals, compiler and diagnostics match the selected Solid build.
• OS: macOS 26.6.2 (25G83); browser cases: system Google Chrome 155.0.8059.40. Server-only/type checks run in Bun 1.4.2.
• Builds/comparison: production fail. rc.13 passes in both builds.

Additional context

Awaiting refresh is part of the public async action flow. A promise that never settles prevents the caller from completing.
