Minimal incorrect example:

-- current
sanitizeBalance "<td>foo<td>bar" == "<td>foo<td>bar</td></td>"

-- correct
sanitizeBalance "<td>foo<td>bar" == "<td>foo</td><td>bar</td>"

-- potentially an option depending on semantics of "balanced"
sanitizeBalance "<td>foo<td>bar" == "<td>foo<td>bar"

If html4 / xhtml5 sanitizing is also desired then separate functions/modules may be needed.
