Copying table using context menu strips off styles.

[Jakub Ś]

Steps to reproduce

1. Paste below code in source mode and switch to wysiwyg

   <table border="1" cellpadding="1" cellspacing="1" style="width:500px">
       <tbody>
           <tr>
               <td style="background-color: rgb(102, 102, 204);">s</td>
               <td>s</td>
           </tr>
           <tr>
               <td>s</td>
               <td style="background-color: rgb(255, 255, 0);">s</td>
           </tr>
           <tr>
               <td style="background-color: rgb(255, 204, 0);">s</td>
               <td style="background-color: rgb(255, 204, 0);">s</td>
           </tr>
       </tbody>
   </table>
   

2. Select cells using mouse and press Ctrl+C or roght-click and select copy
3. Paste table using context menu - right-click somewhere below the table and select Paste (Paste into dialog using Ctrl+V and click OK)

Expected result

Just like in case of keyboard (Ctrl+C, Ctrl+V) table should be pasted with background color and width.

Actual result

Styles are being removed and raw table is pasted.

Other details (browser, OS, CKEditor version, installed plugins)

Problem can be reproduced in Blink and Webkit browsers from CKEditor 4.5.0

Temporary workaround is to use Ctrl+C/Ctrl+V

It possibly can be related with #13884.

[Piotr Jasiun]

This is because of the pasteFilter (​http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-pasteFilter) which is turned on only on Chrome by default. Paste filter removes styles for external paste and is disabled for internal copy and paste. When you use a dialog the paste is thread as external and pasteFilter removes styles.

Fix proposal in ​t/13883.
