Move button embedded in wysiwyg

We have a paragraph that contains an html <figure> tag and when we embed this paragraph in the editor with this module, it includes the following every time it renders this paragraph:

<p><span style="background:rgba(220,220,220,0.5);background-image:url(https://web/core/assets/vendor/ckeditor/plugins/widget/images/handle. png);display:none;"><img height="15" role="presentation" src="data:image/gif;base64,R0lGODlhAQABAPABABAP///wAAACH5BAEKAAAALAAAAAAAAAABAAEAAAICRAEAEAOw==" title="Click and drag to move" width="15" /></span></p>

This does not happen with other paragraphs, only with those containing the html tag.
