[whatwg] Revisiting innerWidth quirks

[Charles Pritchard]

I've noticed, recently, that FF4b8 on Windows has a minimum 
window.innerWidth of 392px.
On OS X, Chrome M10 has a minimum innerWidth of 400px.
IE9p7 has a minimum reported width of 234px.

Height is not restricted so severely.

In FF, at least, using "zoom in" allows the the innerWidth to be 
reduced. This is a helpful trick
for testing out more narrow window widths, such as a 200px width.

I don't know that FF supports matchMedia

As I've noted before, these kind of arbitrary restrictions make it 
difficult to test web apps.

They underscore the growing [unnecessary] divide between mobile app and 
desktop
app development.

environment
in desktop browsers.
