Issue You click an openPopup button inside an iframe. A new popup window appears, you input data and click the close button inside the popup. After 20+ repeated cycles, the popup no longer opens. Errors appear: context / Target closed

Problem Description(What is lost context / Target closed?)
The issue you’re experiencing — popup windows stop opening after 20+ repeated clicks, and you see "lost context" / "Target closed" errors — is the most typical resource leak / context invalidation issue when automating pages with iframes + popups in Playwright.

2. Meaning of the Errors lost context: The browser has destroyed the page / iframe / popup window you were trying to interact with. Target closed: The browser context was recycled, timed out, or exhausted from too many repeated creations without proper cleanup.

3. Root Cause Summary The error only appears after 20+ consecutive operations — this is classic resource leakage. The root cause is:Popup window contexts are NOT being fully released/cleaned up by the browser after closing, and cached iframe handles become stale over time. Eventually, the browser runs out of available contexts → new popups can no longer open → automation fails.

Solution

// Short wait for browser internal async cleanup (Playwright can't detect this)
// 1. Iframe back to interactive state
// 2. Popup renderer process destroyed
// 3. JS event loop idle
// 4. Prevent context overload
await expect.poll(() => popupPage.isClosed()).toBe(true);

await page.waitForTimeout(300);

						

1. Wait for the iframe to return to an interactive/clickable state
2. Wait for the browser to fully destroy the popup’s renderer process
3. Wait for the JavaScript event loop to become idle
4. Prevent rapid repeated actions from overloading the browser context/li>
