* Each testcase MUST have the following fields:

* - targetPropName: The name of the property whose value should be
* affected by |decl|.
*
* And will have EITHER:
* - isInvalid: If set to something truthy, this implies that |decl| is
* invalid and should have no effect on |targetPropName|'s
* computed or specified style.
*
* ...OR:
* - expectedDOMStyleVal: The value that we expect to find in the specified
* style -- in elem.style.[targetPropName].
* - expectedCompStyleVal: The value that we expect to find in the computed
* style -- in getComputedStyle(...)[targetPropName]
* If omitted, this is assumed to be the same as
* expectedDOMStyleVal. (Usually they'll be the same.)
