[BUG] Always launch 2 tabs or 2 windows

[Elverslane]

Context:

• Playwright Version: [0.11.1]
• Operating System: [Mac Catalina]

package.json
{ "dependencies": { "playwright": "^0.11.1" } }

test.js
const playwright = require('playwright');
(async () => {
for (const browserType of ['chromium', 'firefox', 'webkit']) {
const browser = await playwright[browserType].launch({ headless: false });
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('http://whatsmyuseragent.org/');
await page.screenshot({ path:output/example-${browserType}.png });
await browser.close();
}
})();

With default settings and for any browser if launch tests with parameter launch({ headless: false }) can see double window/tab. Its kinda strange
