This can be reproduced from a new blank HTML/Text module instance using the 02.01.00 release from December 18.
Create a new module
Add a one word paragraph
Select the word you entered and format it with italics using the I toolbar button
Toggle back and forth between Source view a few times using the Source toolbar button. You will see repeated orphaned </em> tags are being inserted.
It is much worse if you are editing some content that has multiple paragraphs below the point at which you format the text with italics. It adds <em> and </em> tags repeatedly to paragraphs below the point at which you formatted the text. I've seen cases with hundreds of these redundant and orphaned <em> tags, to the point where Chrome won't complete rendering the page for several minutes.
This has resulted in dozens of pages on my site needing to be repaired to remove all of the <em> and </em> tags. I've reproduced this on Firefox, Safari, and IE all latest versions.
I am running DNN version 07.03.04 (45)
