[Bug] device* media queries are not triggered with viewport emulation

If you want to test sites with media queries, setting the viewport is not enough.

I’ve found that I also need to change the window size to accommodate media queries and accurately reflect what a user would see with certain screen sizes

await chromium.launch({args: [ –window-size=${someWidth},${someHeight}]});

That’s easy enough thanks to your helpful device dictionary.

Am I missing something here?

Is it possible to change the default window size on all browser instances launched by Playwright?

Failing that, are there comparable flags for Firefox and Webkit?

I believe this is now fixed in all browsers 🎉

#1565 fixed this for Firefox.
