A user of Ubuntu 18.04 installed Dolphin using sudo apt install dolphin. However, the pane to enable previews was empty. Installing kio-extras fixed that.

OTOH, if the user also installed gwenview, then kio-extras would have come along.
If it's thought suitable, kio-extras could be added as a dependency/recommend for dolphin.
$ apt rdepends kio-extras
kio-extras
