JEditorPane doesn't recognize CSS vertical-align property

JavaHelp uses the Swing JEditorPane component to display HTML help topics. This component ignores the the following CSS definition, which uses a valid CSS property:

tr {vertical-align: top;}

The result is that we have to specify <tr valign="top"> for every row in our HTML tables, because our style requires top alignment rather than the default "middle".
