I came to know this issue when I tried to add a link in a description in Wix Events. That link is to the same site in Wix. Without this feature, I am afraid that the web designer looks so stupid to the visitor.
I guess that it is relatively easier to add this anchor function in Wix Events so I ask to do this effort first.
This is a simple and basic function in HTML. The fact that Wix lacks this feature suggests that Wix depends too much on client-side codes, which is, of course, consistent with another apparent fact that Wix is too slow.
I wonder if a system as Wix can have other implantation such as generating static HTML documents as much as possible and/or performing most functions in server-side codes.
