[Bug]: page.url() returns empty for shortcut/PWA pages

[Mr-ziqiang]

Version

1.58.0

Steps to reproduce

When connecting to Chrome via chromium.connectOverCDP(), pages opened through Chrome shortcuts (possibly PWA or special app pages) exhibit the following behavior:

• page.url() returns an empty string ""
• page.title() times out indefinitely
• However, native CDP commands work perfectly

1. Open a page via Chrome shortcut (or PWA installation)

   • Example: Right-click Chrome shortcut → Open as specific page
   • Or install PWA from a website

2. Start Chrome with remote debugging:

   chrome.exe --remote-debugging-port=9222

3. Connect via Playwright:

   import { chromium } from 'playwright';
   const browser = await chromium.connectOverCDP('http://localhost:9222');
   const context = browser.contexts()[0];
   const pages = context.pages();
   
   for (const page of pages) {
     console.log('URL:', page.url()); // Some pages return ""
     console.log('Title:', await page.title()); // Times out
   }

4. Observe that shortcut/PWA pages return empty URL and timeout

Expected behavior

Since CDP layer works perfectly:

• page.url() should return the actual URL
• page.title() should return the page title
• Both should work consistently regardless of how the page was opened

Actual behavior

• page.url() returns ""
• page.title() times out
• CDP commands work fine

Additional context

Workaround

async function getURLSafe(page) {
  const url = page.url();
  if (url) return url;

  // Fallback to CDP
  const cdp = await page.context().newCDPSession(page);
  const history = await cdp.send('Page.getNavigationHistory');
  await cdp.detach();
  return history.entries[history.currentIndex]?.url || '';
}

async function getTitleSafe(page) {
  try {
    return await Promise.race([
      page.title(),
      new Promise((_, reject) => setTimeout(() => reject(new Error('timeout')), 2000))
    ]);
  } catch {
    const cdp = await page.context().newCDPSession(page);
    const history = await cdp.send('Page.getNavigationHistory');
    await cdp.detach();
    return history.entries[history.currentIndex]?.title || '';
  }
}

Environment

**Playwright Version**: 1.58.0 (Latest)
**Node.js Version**: 18+
**OS**: Windows 10/11
