When adding blockquote to Fromat dropdown it doesn't work as expected

[Jakub Ś]

To reproduce:

1. Add below configuration options or modify format plugin.

   CKEDITOR.config.format_tags = 'p;h1;h2;h3;h4;h5;h6;pre;address;div;blockquote';
   CKEDITOR.config.format_blockquote = { element : 'blockquote' };
   

2. Refresh the page, you will see blank line at the bottom (adding new entry in language file is optional for tests - tag_blockquote : 'Blockquote')
3. Try to format selection with it.

Results: you can't change the selection with blockquote. This tag is added in new line when there is no selection but it behaves like paragraph - new blockquote is inserted with every enter.

Workaround is to use blockquote button
