Core: use interactive to evaluate dom ready, barring IE6-10.

This is a copy of @timmywil's commit, applied to the 1.x branch. This shouldn't have any effect on the extra browsers 1.x supports due to the doScroll check, so I was hoping it could be added in order to provide the same benefit to other browsers as that commit :)

Fixes gh-2822

Oh yeah, seems like we missed this one. 1.12 and 2.2 should definitely behave the same here.

[timmywil]

Needs the test that was added as well. dabd5ba

[timmywil]

But I agree. Thanks for finding this!

It would be better to cherry pick the change if possible, just to simplify auditing.

"It would be better to cherry pick the change if possible, just to simplify auditing." - happy to do this, though it will need editing the 'Support' line - would you prefer that be done by editing the commit, or a second commit afterwards?
Oh, and the commit message itself too.

[timmywil]

Editing the commit should be fine.

Thanks! Merged.
