The CSS 2 specifications state that the height should automatically be computed if the inner block element specifies the height but a containing block element does not.
Steps to Reproduce Behavior
The following table fails to print beyond the first page unless a height attribute is specified for the outer table.
<HTML>
<BODY>
<TABLE>
<TR>
<TD>
<TABLE height="100%">
<TR>
<TD>
