image_default_link_type does not work for galleries

[jayse83]

After some updated I've noticed all galleries started to point the URL to attachment post instead of image. After some digging it seems that attachment post will appear if no settings were found in the code. I've tried to override this without any luck

I found this and it describes the problem:

Now I find out that this fix does not work for galleries. Even if I have image_default_link_type i the data table the attachment appears as default. And the front generates galleries with attachment post url when the setting is missing in the gallery code from content.
