Specified directory is outside the upload directory

Hi, we are noticing on a few of our sites that when you select the second option to replace all links to image on site, that it will sometimes fail with the message:

Specificed directory is outside the upload directory. This is not allowed for security reasons

It looks like this is coming from setNewTargetLocation() method in classes/replacer.php on line 345.

I’m thinking this may have something to do with the fact that our uploads folder is symlinked. We have our site setup similar to a Roots site, so the uploads folder is symlinked to a shared folder across deployments. I’m thinking maybe the call to realpath() is resolving the symlink or something and then EMR thinks it is outside of the upload directory.
