Standards mode test case

Currently the spec says that the following style should only be applied in quirks mode:

input { box-sizing: border-box; }

It appears that many browsers apply this in standards mode too. IE10 follows the spec and only applies this in quirks mode but we've found a live site that depends on this in standards mode and has a workaround coded for IE.

We propose that the spec should be updated to reflect what browsers do today and we intend to update IE's behaviour to match other browsers (i.e. apply this rule in both quirks and standards mode).

Currently this is likely to block CR since there will not be two interoperable implementations.

Comment 2 Adrian Bateman [MSFT] 2013-01-22 04:59:33 UTC 
It turns out that we overlooked the text that scoped box-sizing:border-box to specific values of the "type" attribute when in standards mode, so the spec is correct.
