Anchor tag with not text is by default not shown in HTML document. Such anchor tags are used for internal purpose.

Importing Html document in Rad rich text box is working as expected, but if same document is converted to RTF first by using RtfFormatProvider or save html imported document as rtf; you will notice such anchor tags are visible in Richtextbox editor.
This behavior make consumer annoying, as he/she is expecting same behavior in standard html document. I checked import/export settings for both RtfFormatProvider and HtmlFormateProvider to stop such anchor tags.
For reference I am attaching sample html document, which contains such anchor tags, but supposed not to be appear in editor. and following RadRichtextbox behvior.
Correct behavior when importing html document
RFT document behavior. (Highlighted anchors need to be hidden)
