[2.6beta] ProtectedSource config doesn't work properly with Smarty

[fournaise]

When using Smarty protection source in FCKEditor 2.6beta : FCKConfig.ProtectedSource.Add( /<\{[\s\S]*?\}>/g ); FCKConfig.ProcessHTMLEntities = false ; true

The following code is broken when swithing between wysiwyg/source edition : <p><a href="{if $a=1}url1.htm{else}url2.htm{/if}">TEST</a></p> <p>{if $a=1}url1.htm{else}url2.htm{/if}</p>

become : <p><a href="%7Bif%20$a=1%7Durl1.htm%7Belse%7Durl2.htm%7B/if%7D">TEST</a></p> <p>{if $a=1}url1.htm{else}url2.htm{/if}</p>

conclusion: Smarty code is protected only in tag and not in attribute.

Is it a bug ? how to avoid this behavior ?
