What issue are you seeing?

In a Codex CLI session running a Go test that uses chromedp, Chrome fails to start. A minimal chromedp smoke test in tests/chromedp_test fails with chromedp run
failed: chrome failed to start. In the same repo, go test -v -count=1 ./tests/reflect_test fails with a panic from chromedp startup.

What steps can reproduce the bug?

Start Codex CLI in repo xxx.
Ask Codex to run: go test -v -count=1 ./tests/chromedp_test.
Observe failure: chromedp run failed: chrome failed to start.

package chromedp_test

import (
	"context"
	"testing"
	"time"

	"github.com/chromedp/chromedp"
)

func TestChromeDpSmoke(t *testing.T) {
	ctx, cancel := context.WithTimeout(context.Background(), 20*time.Second)
	defer cancel()

	allocCtx, allocCancel := chromedp.NewExecAllocator(ctx, chromedp.DefaultExecAllocatorOptions[:]...)
	defer allocCancel()

	bctx, bcancel := chromedp.NewContext(allocCtx)
	defer bcancel()

	var title string
	err := chromedp.Run(
		bctx,
		chromedp.Navigate("data:text/html,<html><head><title>ok</title></head><body>ok</body></html>"),
		chromedp.Title(&title),
	)
	if err != nil {
		t.Fatalf("chromedp run failed: %v", err)
	}
	if title != "ok" {
		t.Fatalf("unexpected title: %q", title)
	}
}

chromedp version. (part of go.mod)

	github.com/chromedp/cdproto v0.0.0-20240202021202-6d0b6a386732 // indirect
	github.com/chromedp/chromedp v0.9.5 // indirect
	github.com/chromedp/sysutil v1.0.0 // indirect

What is the expected behavior?

Chromedp should launch Chrome and the smoke test should pass (title is ‘ok’). The test completes successfully when run outside of Codex on my machine.
