When using the "Auto-Tag" feature, the "ComicInfo.xml" file that is created will have the text formatting from ComicVine.

However, if I would manually edit (to correct a typo or add information) and then save/update the tag using the "Save Tags" button, all of the text formatting get converted to plain text.

It seems that saving tags using the "Save Tags" button will remove all the formatting attributes "< /i >< /p >< h2 > etc."
