This happens when using the append(html) function with a table fragment (e.g. <tr>...) and there is whitespace at the beginning of the html string.

It causes unpredictable results as an invalid html block is assigned to a div tag - in windows firefox 1.5.0.7 it strips out all the tr and td tags

When the function clean() is called (from within jquery) it attempts to detect that the string starts with a table element, and handle this case specially.

This is correct, however, if the string has white space before the first actual tag, the string is not detected as being a table fragment by the function, and so is handled incorrectly.
