Reproduce in every HtmlEditor (ex.:
Write 2 Lines of text, select the first and press 'Bold', switch to 'source view' and
back, select the second line, press 'Bold', switch to 'source view' and see the result:
PHP Code:
<b>line 1</b><br><span style="font-weight: bold;">line 2</span
testet with FF 3 on Mac and Windows - <i> and <u> is the same.

Tried to fix with
PHP Code:
but no change. After a switch to sourceview only <spans> were generated.

This is a big Problem if you want to use the HTML Code to generate a PDF File, where
only b,i,u allowed and noch CSS is suported.
