fix invalidation of sibling combinators in different slots.

This extends the code to deal with sibling invalidation to handle the
case where the flat tree doesn't match the DOM tree. In the test-case
for example, dom is:

 * details
   * summary id=a
   * summary

But flat tree is:

 * details
  * slot
    * summary id=a
  * slot
    * summary
