Works fine with 3

<u>*<u>*<u>*</u></u></u> This is not underlined

Breaks with 4

<u>*<u>*<u>*<u>*</u></u></u></u> This *is* underlined </u></u></u></u></u></u></u></u></u> This is still underlined.

DOM structure ends up like this:

<u>*<u>*<u>*<u>*</u></u></u> This *is* underlined  This is still underlined.</u>

A closing </pre> tag clears the formatting.

This affects all formatting specific tags I tried, e.g. bold, italic, font, big, small, etc. Check URL https://dl.dropbox.com/u/175535/bugs/webkit/nested-formatting.html for test cases

This *does not* affect formatting applied via span style or class atrributes.

<a> tags are also unaffected.

Whether or not this is invalid, this
