1151	FCKeditor not compatible with wikitex extension in mediawiki	x-rayman		"Basically when using both fckeditor extension with the wikitex extension in mediawiki (tested on 1.10) FCKeditor changes the code in the wikitex feeds making them unusable.

You can normally post once but on the second edit FCK edits out the special characters
For example you would post:
{{{
<amsmath>\sideset{}{'}\sum_{n<k,\;\text{$n$ odd}} nE_n</amsmath>
}}}
And that would make the correct equation in mediawiki however if you did edit again or even if the previous option had been used to do a preview when you went to save the wikitex extension would fail because fckedit had changed the characters to:
{{{
<amsmath>\sideset{}{'}\sum_{n&amp;lt;k,\;\text{$n$ odd}} nE_n</amsmath>
}}}


{{{
Before and working:<amsmath>\sideset{}{'}\sum_{n<k,\;\text{$n$ odd}} nE_n</amsmath>
After and broken:  <amsmath>\sideset{}{'}\sum_{n&amp;lt;k,\;\text{$n$ odd}} nE_n</amsmath>
}}}

If you try to use the math tool in fckeditor it incorrectly encases the code in the <math> brackets which also prevents it from rendering.

I think what is needed is for fckeditor to ignore the code inside the special wikitex braces? I've tried this using:
