Hello
I noticed, on a site I am developing that if I mouse over an image in file manager I see a popup preview, which is nice.

However if I open the file manager from a block or composer the pop up preview doesn't show.

Has anyone else seen this or got a suggestion to make the popup preview show. It's happening on a fresh install of v5.6.3.1 too so i'm sure it's not a conflict on the site I am developing.

TIA
Nick
