[Firefox5] : Unable to write in the same line ,After using display none/block on editor.

[Jakub Ś]

1. Place 1111.html file in samples folder.
2. Open file in a browser
3. Click inside editor and start typing (type two words, you have got 5 seconds:))
4. After editor reappears, cursor appears at the beginning of typed text but If start typing without changing cursor location old text jumps one line down, so that you have two lines of text in two paragraphs.

This issue has been reproducible in Firefox5 from CKE 3.3.1

This issue is related to #5842

A workaround to this particular bug brought by @garry.yao. Below is the modified code for 1111.html

var editor = CKEDITOR.appendTo( 'editor1' );
	setTimeout( function()
	{
		var sel = editor.getSelection();
		sel && sel.lock();
		document.getElementById( 'editor1' ).style.display = 'none';
		setTimeout( function()
			{
			document.getElementById( 'editor1' ).style.display = 'block';
			editor.getSelection().unlock( true );
		}, 1000 );
	}, 5000 );

Second workaround. This one handles both #5842 and #8209. It was brought to you by @garry.yao. Below is the modified code for 1111.html

var editor = CKEDITOR.appendTo( 'editor1' );
setTimeout( function()
{
	var focused = editor.focusManager.hasFocus;
	if ( focused )
	{
		var sel = editor.getSelection();
		sel.lock();
	}

	document.getElementById( 'editor1' ).style.display = 'none';
	setTimeout( function()
	{
		document.getElementById( 'editor1' ).style.display = 'block';

		if ( focused )
		{
			editor.focusGrabber.focus();
			setTimeout( function() { editor.getSelection().unlock( true ); } );
		}
	}, 1000 );
}, 5000 );
