 If cursor is placed between <iframe> and </iframe> in text mode each time
 I switch from Text to Visual mode what i guess (from editor.js code) is
 bookmark is added and not removed, it just keeps stacking with each
 change.

 code that appears between tags is:

 {{{
 <span data-mce-type="bookmark" style="display: inline-block; width:
 0px; overflow: hidden; line-height: 0;"
 class="mce_SELRES_start"></span>
 }}}

 Here is example to replicate bug:

 {{{
 <iframe width="100%" height="450" style="border: 0;"
 src="https://www.google.com/maps/embed/v1/place?key=xxxx&q=NewYork"
 frameborder="0"></iframe>
 }}}

 Note: If possible, please use valid key and query, i had to remove them
 for demonstration, but bug happens even with this code.

 Paste that code in Text mode, click between >< of "></iframe>" and switch
 to Visual mode, then switch back to Text mode (do not click anywhere in
 Visual mode). Every time this is repeated, it just keeps adding mentioned
 code.

 My humble guess is that this is happening because Visual is generating map
 preview from iframe tag so it can not detect that same place in code when
 it is switched back to Text mode.
