[BUG] Firefox Timeout while waiting for popup

Context:

• Playwright Version: 0.11.1
• Operating System: Mac 10.13.6
• Node.js version: 12.14.1
• Browser: Firefox
• Extra: We are using 0.11.1 Playwright for compatibility with Mac Sierra, as I understand newer Playwright versions do not accept Mac Sierra

Code Snippet

Help us help you! Put down a short code snippet that illustrates your bug and that we can run and debug locally. For example:

it.each(['chromium', 'firefox'])(`${testTitle} [%s]`, async browserType => {
    const playwright = new PlaywrightUtilStructure(browserType)
    await playwright.launchBrowser() // creates browser & context instances
    await playwright.launchApp() // goes to page
    try {
      const landingPage = new LandingPage(playwright.page) // util functions, not critical
      // .. other validation
      const [popup] = await Promise.all([
        playwright.page.waitForEvent('popup'),
        await landingPage.clickLoginItem(), // Click triggers a popup.
      ])
      // The promise resolves after 'domcontentloaded' event.
      await popup.waitForLoadState('domcontentloaded')
      console.log(await popup.title()) // Popup is ready to use.
    } catch (err) {
      await playwright.screenshotCloseBrowserThrow(testTitle, err)
    }
    // Close after finished test success
    await playwright.closeBrowser()
  })

Describe the bug

We have this code running for chromium & firefox (see above via it.each) and chromium passes fine. The log line prints the expected name of the popup, and when running in headless=false mode we can see the popup open and can confirm it matches the log. On firefox however, the code hangs during the Promise.all phase with the following:

TimeoutError: Timeout exceeded while waiting for popup

      18 |       const [popup] = await Promise.all([
    > 19 |         playwright.page.waitForEvent('popup'),
         |                         ^
      20 |         await landingPage.clickLoginItem(), // Click triggers a popup.
      21 |       ])
      22 |       // The promise resolves after 'domcontentloaded' event.

But I can confirm the popup is appearing (and not even slowly).

I recognize this might be a “get on the proper version of Playwright” kind of issue, considering we’re not using even the 1.0.0 version, but was hoping someone might have input.

@aslushnikov That is accurate, but on removal nothing changes. Thanks for spotting it though.

I’m delighted to announce that even though my use of playwright@next earlier did not succeed, my use of the official playwright@1.4.2 did succeed, on both Chromium & Firefox (right in the middle of my trying to make a repro which also succeeded for both)
