I figured it out!
This has been bothering me for years. I finally just sat down and solved the problem. Basically, VS has this little known feature where you can navigate through code lens with just your keyboard. If you press Alt for a couple of seconds, you will see numbers just like the ones that appear at the top of your screen above your current method. To fix it, just long press Alt again and the number should go away. If you have many VS instances open you might have to go through them one by one.
