Hi Hans

Yes, it does that. You can configure your way out of it:

A short follow-up to the solution suggested on the ckeditor-forums:

protectedSource does preserve the code, but it also prevents the icons from being rendered in the WISIWYG area after switching to source or simply reopening the paragraph:

config.protectedSource.push( /<i class[\s\S]*?\>/g );
config.protectedSource.push( /<\/i>/g );

Adding the following line outside the CKEDITOR.editorConfig function line preserves the empty tags:

CKEDITOR.dtd.$removeEmpty['i'] = false;

In order to preserve the class and style attributes, I added the following:

config.extraAllowedContent = 'i(*){*}[*]';

To make the fontawesome function in DW9 work properly with our config, I added those two lines - except I allowed span-tags instead of i-tags.
