You mean when you jump to that point in the text?
That's because when you jump to a location in the document in Mobi, it starts parsing the HTML from that precise point, so if you're "inside" a bold, header, or any other tag, it doesn't know. It's up to the document creator to ensure that all anchor tags are placed outside such formatting tags.
