/** Test for correct ExpectEndProperty calls in CSS parser **/
/*
* Inspired by review comments on bug 378217.
*
* The original idea was to test that ExpectEndProperty calls are made
* in the correct places in the CSS parser so that we don't accept
* garbage at the end of property values.
*
* However, there's actually other code (in ParseDeclaration) that
* ensures that we don't accept garbage.
*
* Despite that, I'm checking it in anyway, since it caught an infinite
* loop in the patch for bug 435441.

* tested
