 " " is appened in front of a table when switching from text editor to
 visual editor if the cursor is at the begining of the textarea or the
 textarea doesn't have focus.

 To reproduce this bug, create a new post, choose tab "text editor", add
 the following:
 {{{
 <table>
 <tbody>
 <tr>
 <td>hello</td>
 </tr>
 </tbody>
 </table>
 }}}

 Then save draft and change to "visual editor".

 Now the table has a blank line above and if you return to text editor you
 see this:
 {{{
  
 <table>
 <tbody>
 <tr>
 <td>hello</td>
 </tr>
 </tbody>
 </table>
 }}}

 This bug happens in 4.9.x, not in 4.8.5.
