Affects IE only.

Another case for this problem:

1. Load the following content with selection:

   <strong>some <a href=" http://ckeditor.com">[sample ]</a></strong><a href=" http://ckeditor.com">link</a>
   

2. Remove 'Bold' style from the selection.
   • Actual Result: The link element is not merged on output.

The "ignore" variable is only set, it isn't used in any other place so it can be removed.

The check for "Merge empty links but not anchors." isn't needed. The merging should really help if there are two anchors together with the same name, that's a problem (only one of them will work) and merging them will fix the problem.

The "ignore" variable is only set...

Used on L913.

[Alfonso Martínez de Lizarrondo]

My comment was just that it's set on L913 but it isn't used in any other place so we can skip the assignment.

Fix that before committing.

Fixed with [5396].
