The comment is still valid for caption and tHead.

[rwlbuis, 2016/09/15 14:32:33]

Done.

-        // an exception, it should just remove the old caption/thead/tfoot.
         shouldThrow("t.caption = null");
         shouldThrow("t.caption = document.body");

         shouldThrow("t.tHead = document.body");

+        shouldNotThrow("t.tFoot = null");

We should confirm that t.tFoot is removed from |t| by t.tFoot=null with non-null
t.tFoot.

[rwlbuis, 2016/09/15 14:32:33]

Done.

         shouldThrow("t.tFoot = document.body");
 
         shouldThrow("t.insertRow(-2)");
