Magic line not displayed with elements floated/aligned to the right

[Jakub Ś]

1. Insert below code into editor (div or table)

   <div style="float:right;">TEST</div>
   
   <div align="right">TEST</div>
   
   <table align="right">
   <tr><td>TEST</td></tr>
   </table>
   
   <table style="float:right;">
   <tr><td>TEST</td></tr>
   </table>
   

2. Hover below/over the element

Result: No magic line is displayed and there is no possibility exit the element.
