window.innerWidth should return valid value, when CSS viewport descriptors applied. Test is attached.

Might need splitting as it actually solves two problems:
1) initial viewport size detection in webcore
2) appropriate frame view initialization in WK2 WebPage

However those fixes are very close so put them the same patch so far.

Isn't it better to use the description from the spec? also link to the spec in the changelog

I would add a newline before this

I would like some tests that uses a non-1.0 deviceScaleFactor. I think it is possible to change that in tests.

Another question, doesn't this affect viewport meta as well? That would affect the ifdef's

I don't think it is possible to set/unset viewport meta properties for the same doc, so not I guess
