Wrong behavior when applying object styles - existing inline styles are removed

[Wiktor Walc]

1. Go to ​http://ckeditor.com/latest/samples/replacebycode.html
2. Press "New Page" button
3. Insert a table
4. Apply "Borderless Table" style

Result

Width definition is removed (a side effect i that now it is hard to insert content into cells).

Expected result

The following style definition should only add and/or override styles that are defined in the styles object. Other styles that were applied already to a table shouldn't be lost.

{
    name: 'Borderless Table',
    element: 'table',
    styles: {
        'border-style': 'hidden',
        'background-color': '#E6E6FA' 
    } 
},

If my intention is to remove 'width' when applying this style, I should be able to define it as width: '' or width: null etc.

Actually, so far this has been done by design, so the proposed way of handling styles in ticket is rather a new feature than a bug.
