[Webkit] Paste elements carries applied style

[Garry Yao]

1. Append the following styles to the content.css file:

   p,strong
   {
   	border: 1px dotted #000;
   }
   
   

2. Load the editor with following content:

   <p><strong>paragraph1</strong></p>
   <p>paragraph2</p>
   

3. Copy all content and paste at the end of doc.

• Actual Result: The computed style of the content is pasted as inline style.

Another different way to reproduce it:

1. Load the editor with the following:

   <p>para[graph</p>
   <h1>head]ing1</h1>
   

2. Copy the selected text;
3. Put cursor at the end of heading element;
4. Paste the clipboard content

• Actual Result: The first pasted line has a different font style with the paste in block.
