editor.getSelected().toHTML() is not consistent

Hi everyone,

I created a new component type, 'html-block', which is a component in which you can add your html code. I added an 'Edit' button to the toolbar, to enable the user editing the added html code. In order to show the html code of the component in the modal, I am using the function 'editor.getSelected().toHTML()';

The problem is that, sometimes the code returned is per example: <div><h1>h1</h1></div> (which is what I need, since I need the exact code that the user added at first), and sometimes it returns something like that: <div id='135'><h1>h1</h1></div> (with an id added automatically). I also tried to use 'editor.getSelected().em.getHtml()' but the same issue occurred.

How can I solve that and retrieve the exact html code that the user entered ?

Thank you in advance.
