Change in Dropbox Embedder behaviour

Hello,

It used to be possible when using Dropbox Embedder with a link to folder reliable navigation in that folder and preview all files in pointed folder - all files that Embedder may handle of course.

Now Dropbox Embedder may handle, in correct way, only link pointing to particular file directly! Is this intended behavior or some bug? 🧐

When navigating in folder and try open a file inside, new frame (window or tab) gets up now. Why? Would be so from now on? If in use is a link to file derived from link to containing folder, display fails completely! Link to the same file that's created for the particular file succeeds. Both link types open correctly in browser. Is this normal? 🤔

Thanks.
