How fix an icon on bookmark in Nemo?

Hi,

picture, rather than words…


In green, it’s good : places applet on the left and workspace switcher on the right find a matching icon for :///recent.
In orange, nemo’s bookmark shows a missing element icon.
In red, a missing translation ( same in dropdby ).

Tested with Papirus and Pocillo, on UB 19.10.

So is there a way to give an icon to a nemo’s bookmark ?
