WordPress 4.7

Previewing is not working properly for codeblock (Advanced Layout Editor)

When viewed the codeblock is correctly paragraphed but now since 4.7 WordPress the preview changes view is missing the paragraph markers.

Create a codebock with:

:START OFOF BLOCK

<iframe style=”border: 0;” src=”//www.youtube.com/embed/T0vCwyrlF60?rel=0&enablejsapi=1″ width=”340″ height=”191″ allowfullscreen=”allowfullscreen”></iframe>

[av_button label='Buy Now' link='manually,/conversion-software/pdf-to-tiff-converter/license/' link_target='' size='small' position='left' icon_select='yes' icon='ue859' font='entypo-fontello' color='custom' custom_bg='#149172' custom_font='#ffffff'] [av_button label='Trial Download' link='manually,/conversion-software/pdf-to-tiff-converter/tiff-image-printer-evaluation-request/' link_target='' size='small' position='left' icon_select='yes' icon='ue8b0' font='entypo-fontello' color='theme-color' custom_bg='#444444' custom_font='#ffffff']

:END OF BLOCK

If you view published page you <p></p> markers, if you preview the page they are missing.

Was not a problem before WordPress 4.7.

I am on the latest EnfoldVersion: 3.8.4.

Any thoughts on why this is happening. It making it hard to do changes.
