Pasting pure text in Chrome causes weird results

[Wiktor Walc]

1. Open a sample with ACF disabled (e.g. the magicline sample).

2. Paste the following in source mode:

<table border="0" cellpadding="0" cellspacing="0" style="width:100%">
  <tbody>
    <tr>
      <td style="color: #5f2351; font-size: 18pt;">
        Hello &amp; welcome to K-talk
      </td>
    </tr>
  </tbody>
</table>

3. Switch to WYSIWYG mode.

4. Copy "Test paste" string from some plain text editor (e.g. Notepad on Windows)

5. Place the cursor at the end of the text and press the keyboard shortcut to paste (CTRL + V).

6. The result is (wrong):

   <table border="0" cellpadding="0" cellspacing="0" style="width:100%">
     <tbody>
       <tr>
         <td style="color: #5f2351; font-size: 18pt;">
           <font color="#666666">
             <span style="font-size:10px">
               Hello &amp; welcome to K-talk
             </span>
           </font>
           Test paste
         </td>
       </tr>
     </tbody>
   </table>
   

7. However, if you paste the same content using the "Paste" button in CKEditor, the result is different (correct!):

   <table border="0" cellpadding="0" cellspacing="0" style="width:100%">
     <tbody>
       <tr>
         <td style="color: #5f2351; font-size: 18pt;">
           Hello &amp; welcome to K-talkTest paste
         </td>
       </tr>
     </tbody>
   </table>

Confirmed on Google Chrome (Win, Linux, Mac), happens in CKEditor 4.0 - 4.4.6. Works fine on CKEditor 3.6.6.2 and on plain contenteditable.

I couldn't find any other markup different than tables that would cause similar issues.
