Styles combo drop down list not refreshed

[Webunity]

Situation:

• CKEditor 3.4.2
  
• Custom styleset loaded
  
• removeFormatTags added to include (e.g. remove) block elements
  

Following configuration was used:

<textarea name="editor1" rows="8" cols="60">&lt;h1&gt;Initial value&lt;/h1&gt;</textarea>
<script type="text/javascript">//<![CDATA[
CKEDITOR.replace('editor1', {
		"language": "en",
		"skin": "v2",
		"width": "100%",
		"height": "500",
		"resize_enabled": false,
		"baseHref": "http:\/\/127.0.0.1\/",
		"forcePasteAsPlainText": true, 
		"removePlugins": "elementspath",
		"removeFormatTags": "b,big,code,del,dfn,em,font,i,ins,kbd,q,samp,small,span,strike,strong,sub,sup,tt,u,var,h1,h2,h3,h4,h5,h6,hr",
		"toolbarCanCollapse": false,
		"stylesSet": "default:http:\/\/127.0.0.1\/\/rewrite.php\/cms\/ckeditor\/styles"
	});
//]]></script>

The loaded styleset:

CKEDITOR.stylesSet.add('default', [ { name: 'CMS - Accordeon titel element', element: 'div', attributes: { 'class': 'wuaTitle' } }, { name: 'Koptekst 1', element: 'h1' }, { name: 'Koptekst 2', element: 'h2' }, { name: 'Koptekst 3', element: 'h3' }, { name: 'Koptekst 4', element: 'h4' }, { name: 'Koptekst 5', element: 'h5' }, { name: 'Koptekst 6', element: 'h6' } ]);

BUG description:

• Select the entire tag
  
• Click on the removeFormat button
  
• This removes the H1, but leaves the style marked in the stylescombo.
  
• So the styles combo did not get refreshed/updated in FF 3.6.12.
  

Does NOT happen (e.g. behaviour is correct) when the H1 is wrapped in a container as shown below:

<textarea name="editor1" rows="8" cols="60">&lt;div&gt;&lt;h1&gt;Initial value&lt;/h1&gt;&lt;/div&gt;</textarea>

Cause & sollution:
After searching and diggin into the code for a huge ammount of time..
It seems that after clicking the removeFormat button, the "selectionChange", attached in the stylescombo (onRender) is not fired.
Getting this event to fire (duplicating code from _source/plugins/tabletools/dialogs.js:525) was unsuccesfull.
I managed to get it working by doing the following 2 changes, but it could be nicer...

./_source/plugins/stylescombo/plugins.js

onRender : function()
{
	function updateCombo( ev ) {
		var currentValue = this.getValue();
		var elementPath = ev.data.path,
		elements = elementPath.elements;

		// For each element into the elements path.
		for ( var i = 0, count = elements.length, element ; i < count ; i++ )
		{
			element = elements[i];

			// Check if the element is removable by any of
			// the styles.
			for ( var value in styles )
			{
				if ( styles[ value ].checkElementRemovable( element, true ) )
				{
					if ( value != currentValue )
						this.setValue( value );
					return;
				}
			}
		}

		// If no styles match, just empty it.
		this.setValue( '' );
	}

	editor.on( 'selectionChange', updateCombo, this);
	editor.on( 'removeFormat', updateCombo, this);
},

./_source/plugins/stylescombo/plugins.js (line 120)

	editor.getSelection().selectRanges( ranges );
	editor.fire( 'removeFormat', { path : new CKEDITOR.dom.elementPath( editor.getSelection().getStartElement() ) } );

Much simplified reproducing steps here:

1. Open "Styles" combo and apply the "Deleted Text" style to any text selection;
2. Click on "Remove Format" button, note that inline label is changed on "Styles" combo, then open the combo again;

• Actual: "Deleted Text" option keep marked on the list.

The tc from first comment is still reproducible on trunk.

Confirmed to be regressed by Firefox since version 7.

Still reproducible in Firefox 11
