This ASSERT is still valid AFAICT so we should keep it.

Let's also add the following assert to catch any misuse:

ASSERT(RuntimeEnabledFeatures::css3TextEnabled())

Umm... I agree. I'll recover ASSERT.

     CSSPrimitiveValue* eachLineValue = toCSSPrimitiveValue(valueList->item(1));
     if (eachLineValue) {
-        ASSERT(eachLineValue->getValueID() == CSSValueWebkitEachLine);
