cjbolg art. editor not handling 'sourcerer' plugin

Hi,
I use sourcerer (nonumber) plugin to embed video's in my articles.
Sourcerer works with the following tags {source} 'embedded code goes here' {/source}

Just noticed that when editing an article with the cjblog editor, the embedded video is 'stripped' > the result is as follows: {source} {/source}

When using the Joomla article editor it respects the sourcerer plugin.

Is this a known 'issue', can I change this behavior?

thanks in advance.
regards,
Ruud.
