Fix for onbeforeactivate feature test to support Win8
storechild-lm: yui3 [ie10] $ git show f771c6e6629d3d4ac6cee8408cdb9b373827c432
commit f771c6e6629d3d4ac6cee8408cdb9b373827c432

Fixed onbeforeactivate feature test so that it works in Win 8 packaged apps.
In Win 8 packaged JS app environments, innerHTML cannot contain inline handlers,
which the feature test was relying on.
