Comment (by xkon):

 I've been doing some tests trying to tackle this but without getting any
 results as I don't even know where to start, the only files I didn't go
 through was the tinyMCE ones.

 Extra information:

 I've found out that there's always an extra `<a></a>` even when using the
 Link button from the editor ( not editing with the Image Editor ), if you
 do it while on Visual tab and just change to Text you will always see an
 extra empty <a> that is always the 'last' used. So the extra `<a>` gets
 generated either way you try to edit the 'current' link.

 Apparently when you are trying to change the link instead of getting
 replaced it is like creating a new one and moving the image in there, thus
 leaving the old one empty without an `<img>` tag in it. Some times when
 you hit the Update button it gets removed but sometimes it doesn't (
 usually it does not ).

 I don't know if this is a tinyMCE thing or there's somewhere an extra
 function when we Update the posts / pages that doesn't get triggered
 always.

 Hopefully this can help a bit to get this fixed.

 Best regards,
 Konstantinos
