Stop adding custom attributes

[speculees]

Hello, inside of tinymce editor I have the following HTML:

<p data-merged="yes">some lorem ipsum text </p> <p data-merged="yes">Lorem ipsum dolor sit amet,pri salutatus tincidunt reformidans id, ex nec magna epicuri delicata. Sea ne melius deseruisse, vix ut libris causae tractatos. <strong data-merged="yes">Vix </strong> facete virtute eu, ea iriure aliquip adversarium usu. Augue animal nostrud ei mei.</p>

I need to know which new elements are added. So when I press enter after "some lorem ipsum text" i expect to get the following html:

<p data-merged="yes">some lorem ipsum text </p> <p>&nbsp;</p> <p data-merged="yes">Lorem ipsum dolor sit amet,pri salutatus tincidunt reformidans id, ex nec magna epicuri delicata. Sea ne melius deseruisse, vix ut libris causae tractatos. <strong data-merged="yes">Vix </strong> facete virtute eu, ea iriure aliquip adversarium usu. Augue animal nostrud ei mei.</p>

However I get:

<p data-merged="yes">some lorem ipsum text </p> <p data-merged="yes" >&nbsp;</p> <p data-merged="yes">Lorem ipsum dolor sit amet,pri salutatus tincidunt reformidans id, ex nec magna epicuri delicata. Sea ne melius deseruisse, vix ut libris causae tractatos. <strong data-merged="yes">Vix </strong> facete virtute eu, ea iriure aliquip adversarium usu. Augue animal nostrud ei mei.</p>

I need to get the <p>&nbsp;</p> without custom data-merged attributes so I can know which elements are new.
