Formatting tags like INS and DEL are not preserved when a text is copied and pasted in the same page.

Reproducible: Always

Steps to Reproduce:
1. Go to the Midas demo page.
2. Switch to "View HTML Source".
3. Set the content to: <strong>abc <ins>123</ins> xyz</strong> after
4. Uncheck "View HTML Source".
5. Copy "2" from "123" and paste it anywhere inside "after".
Actual Results:  
<strong>abc <ins>123</ins> xyz</strong> afte<strong>2</strong>r

As you can see, only the STRONG tag had been copied.

Expected Results:  
<strong>abc <ins>123</ins> xyz</strong> afte<strong><ins>2</ins></strong>r

I think Midas doesn't copy formatting tags that are not "strictly" in-line. We know that INS and DEL elements can contain block-level elements. For instance, if we use CSS instead of formatting tags:

<strong>abc <span style="text-decoration: underline;">123</span> xyz</strong> after

the underline style is copied along with the bold style:

<strong>abc <span style="text-decoration: underline;">123</span> xyz</strong> afte<strong><span style="text-decoration: underline;">2</span></strong>r
