Map Thumbnails do not refresh automatically on update

[Gnafu]

Go to the main page and change a thumbnail.
The new thumbnail is not visible until reload (vie page refresh or search)

Could not reproduce it.

User is not admin
Tested on dev with Chrome

The thumbnail briefly flashes as it was updated but then the old one is displayed.
In the video, to see the new thumbnail I trigger an empty search.

Ok, i've tried with an admin user, maybe that's the reason. I'll check this
