[Webkit] SelectAll incorrectness

[Garry Yao]

It's unable to select all document content with either keyboard Ctrl-A or Select All button, the selection range is actually just covered inline element content.

Reproducing Procedures

1. Open the replace by code example page;
2. Make document content and selection as following by double click on cell:

   <p>
   	<span style="font-size: 24px;">text</span></p>
   

   1. Click on 'Select All' button and followed with 'delete' key;
   2. Type some random text;
   • Actual Result : the entered text shared the same font size as previous.
