Pinboard: When using ajax links the loaded entries are not displayed correctly

Hello there,

I’m having the following problem when using the “ajax links” option for loading more posts: the items are loaded correctly, but are not ordered as one would expect (at the end of the previously loaded items). Instead they appear to be loaded behind the other entries. I’ve tested this with Chrome and Firefox. When using the infinite scroll things work fine.

Here is the address of the site with the problem:

Thanks for your help!
