PDF attachments no longer show a thumbnail of the first page - just a grey box

Question

If I use the old editor I get a nice thumbnail preview of the first page of the PDF as shown on right

If I use the new editor I get a grey box showing the title and size as shown on left.

I prefer the thumbnail image over the grey box.  Hoping the new editor has this feature and I just don't know how to do it yet.

My current findings which could hopefully helpful workaround for all who's missing some function in "new editing experience':

if you were using old confluence with old experience and then migrated your spaces and pages to the new one, all migrated pages remain under the "old experience"! Moreover, if you'd then clone your migrated pages in your new confluence, those clones will also be with old experience :)

of you need more details, just shout

We are also extremely lacking this function in the new cloud editing experience, along with the ability to drag-n-drop and resize the attachments.

Are there plans to restore this functionality for the new editing experience?

I agree that this is very annoying. With the new editor we also lost the ability to choose to display the thumbnail image in different sizes, and to me the most important option we've lost -> just display the attachment as a link (see here and here for logged issues)! Now we're stuck with ugly grey boxes no matter what.

Another side effect is that we can no longer add attachments in lists (bulleted or numbered); see issue here.
