You can try this config.protectedSource.push(/]*><\/i>/g);

From official documentation

{Array} CKEDITOR.config.protectedSource Since: 3.0

List of regular expressions to be executed on input HTML, indicating HTML source code that when matched, must not be available in the WYSIWYG mode for editing.

config.protectedSource.push( /<\?[\s\S]*?\?>/g ); // PHP code

config.protectedSource.push( /<%[\s\S]*?%>/g ); // ASP code

config.protectedSource.push( /(]+>[\s|\S]*?]+>)|(]+/>)/gi ); // ASP.Net code

CKEDITOR.on( 'instanceReady', function( ev )
{
// turn off excess line breaks in html output formatting for blockquote tag.
// In same way you can correct any tag output formating

ev.editor.dataProcessor.writer.setRules( 'blockquote',
{
  indent : false,
  breakBeforeOpen : false,
  breakAfterOpen : false,
  breakBeforeClose : false,
  breakAfterClose : true
});
});
