+ <h1>Tests for redistribution of table height to row group height.</h1>
+ <p>This algorithm has not been standardized. Browsers implementations disagree a lot.
+ Legacy Chrome used to always distribute all the height to the first tbody.</p>
+
+<pre class=error>Major incompatibility: Legacy:
+- ignores any height set on sections.
+- does not size the table unless section has a TR
+- does not grow sections without TDs
+- only distributes height to the 1st tbody
+FF
+- does not prioritize thead for height distribution most of the time.
+- y offset of multiple tbodies can be incorrect.
+</pre>

+<h2>One TBODY</h2>
